Compile time filesystem access?

[David Nadlinger]

Be careful, though, the import expression (understandably) expects a 
compile-time string, which means that you can't directly use it from 
CTFE (e.g. to open additional files included by the IDL file you are 
parsing), but instead have to go back to compile-time land and then pass 
the contents back to CTFE in convoluted ways…
