Hi!

Is there any simple way to programmatically expand a macro? I already have a PoC that uses syntax-local-binding, but that is quite complex. 

Say I have a macro called (hej body ...), can I in any simple way expand (body ...) so that all macros within are expanded? Without relying on syntax-local-value and doing it all myself, that is.

Best regards
  Linus Björnstam

No, Guile has no such facility

There was a previous discussion of this, here

There is a small macro tool that will expand the arguments before calling
the macros body. Forgot its name. This is closest you get with what you are
asking for. Its a really cool macrology based on syntax rules. Its included
in guile standard.
