Programmatically expand macros

[Linus Björnstam]

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
