[TxMt] language mode is not per tab/file?

[Greg Humphreys]

Along those lines, I have a feature request which I would use  
frequently, which is that a single file could be multi-mode based on  
some very simple regular expression matching.

For example, I have lots of files that look like this:

LaTeX stuff
LaTeX stuff
LaTeX stuff

<<some string>>=
C++ stuff
C++ stuff
C++ stuff
@

LaTeX stuff
LaTeX stuff
LaTeX stuff

<<some other string>>=
C++ stuff
C++ stuff
C++ stuff
@

and so on.  I'd like the sections to be syntax highlighted (hilit?)  
according to their respective styles, and when the cursor is between  
the <<...>>= and @, I'd like to edit in C++ mode with all the  
associated macros / tab expanders, and in LaTeX otherwise.

I'm mainly just a user of TextMate; I haven't really extended it in  
any meaningful way; is this something that an experienced end-user  
could do, or would it require a fundamental change to the core?

Allan?  Thoughts about this?  I imagine it would be implemented as a  
"meta-mode", which is just a mode that tells TM under what  
circumstances it should interpret blocks as other modes.
