- Shifting data out of sbuffs is expensive because we need to update every nested sbuff, and every marker associated with them.
- Passing terminals and unescape callbacks into functions leads to massive complexity, and needing to allocate memory to allocate merged tables of token sequences.
- Last matched token isn't stored anywhere, so the caller of a parsing function needs to check the current position of an sbuff against its tokens.

| Operator | Description
| = | Set the attribute to the contents of the _<rhs>_, if the _<attribute>_ does not exist. If the attribute already exists, nothing is done. If the attribute does not exist, it is created, and the contents set to the value of the _<rhs>_
-| := | Override the attribute with the contents with the _<rhs>_. If the attribute already exists, its value is over-written. If the attribute does not exist, it is created, and the contents set to thex value of the _<rhs>_
+| := | Override the attribute with the contents with the _<rhs>_. If the attribute already exists, its value is over-written. If the attribute does not exist, it is created, and the contents set to the value of the _<rhs>_
| += | Perform string append. The contents of the _<rhs>_ are appended to the _<attribute>_.
| -= | Inverse of string append. The contents of the _<rhs>_ are deleted from from the _<attribute>_, if the `_<rhs>_` is a suffix of _<attribute>_
| ^= | For `string`, performs a "prepend" operation. The contents of the _<rhs>_ are prepended to the _<attribute>_. This is the opposite of `+=`.

In some cases, as when using `%exec(...)`, it is impossible to determine which arguments are filenames, and which are simple strings. This function allows the server to safely pass in a filename to external programs.
-The returned filename is guaranteed to be safe to use. Any portion of the filename which is taken from a "safe" source (i.e. configuration files, etc. controlled by an administator) is used as-is. Any portion of the filename which is taken from an "unsafe" source (i.e. network apckets) is escaped. The result is that characters like `/` in unsafe inputs cannot be used to perform directory traversal attacks.

documented below.
Each expansion given here can be prefixed with one or more dot (`.`)
For example `'filename'` is the name of the current file being
executed, while `'..filename'` is the filename of the parent request.

Which filename is currently being executed.
-== %interpeter('line')
+== %interpreter('line')
The line number in the current file being executed.
-== %interpeter('processing_stage')
+== %interpreter('processing_stage')
Which section of a virtual server is processing the request.
-== %interpeter('module')
+== %interpreter('module')
The current module being executed. If the expansions is done in an
`unlang` statement and outside of any module, it returns the name of
the previous module which was executed.
-== %interpeter('processing_stage')
+== %interpreter('processing_stage')
Which section of a virtual server is processing the request.
-== %interpeter('rcode')
+== %interpreter('rcode')
The current interpreter return code, e.g. `handle`, or `ok`, etc.
-== %interpeter('server')
+== %interpreter('server')
The name of the virtual server which is running the request.
The INFO messages are always logged.
-== %log.watn(_string_)
+== %log.warn(_string_)
Logs a message at a WARN level. This function returns nothing.
