Re: [ANN] Lust (Lua String Templates)

Cool, thanks for getting this out, Wes!

Another possibly interesting little fact about Lust's implementation is that each template defined is internally reified into a program by generating Lua code specialized to the template, which in some cases can significantly speed up processing.

With this feature, it's possible to turn the templates themselves into a description of a state machine, which is extremely useful for complicated templates such as those that synthesize code from an AST.  See the examples/dispatch.lua example script for a short demo of this design pattern.
