Source code debuggers are important. If the source code and target
language are close then debugging the target language is not 
difficult. C source debuggers work well with translators like
lex and yacc. However Ratfor is sufficiently different from
FORTRAN that I have trouble debugging it. Debugging assembler
from C source is not worth the effort for the applications that
I develop.

Hmm. Sounds like the "#line" directive. This is really more 
useful for diagnostic messages than source code debugging.

I too would like to see the generated C code. If the C++ source
and generated C are close then I might buy Comeau C++ otherwise
I'll wait for a C++ that has a source code debugger.
