I'm inferring that your #lang probably uses a non s-expression syntax.

If your #lang has a non-s-expression syntax, then you will need to need either 
use the 'language-info syntax property with or use a configure-runtime 

The first method is introduced here, and it's the one I've used before

But either way, you would want to override the current-read or the 
current-readtable parameter to use your new reader.

How are you implementing your reader? Are you using syntax/module-reader, or 
are you providing the read, read-syntax, and get-info functions directly? If 
you're providing them directly, are you generating them using a function like 
make-meta-reader, are you using a readtable, are you using a parser library, or 
something else?
