Why not? If the argument is static? (A string literal, surely 
this shouldn't be a problem and usually what is used?)


void myThrowingNogcFunc(string s)() @nogc
{
         static const exc = new Exception(s);
         throw exc;
}


?

I too am looking for nogc exceptions.

How about simply setting aside a 100kb of memory as a pool for 
exceptions. Seems like a lot but still under 640kb, hell, even 
1MB would still be tiny.

After all, it's not like exceptions are common or happen in 
complex ways.

Does anyone have a proper solution to this problem? I'd like nogc 
exception handling with run-time generated args.
