Well you can either open the class:
open C_hack;
or you can define your own ignore .. it's only a one line definition after all
:)
You can also inherit it into a scope or use the rename facility, but that's
really overkill.

I am working on some tools related to this. Basically Felix has a "trace"
feature which can
be used for instrumentation. You should be able to add manual "trace" call or
tell
the compiler to add them, say, every function call.
My idea is that if you're tracing, Felix will start a thread which runs a
webserver.
Then you can look at the program execution with a browser.
Similarly, I am writing a text editor in SDL (portable graphics).
This could be morphed into a debugging console, again,
connecting to the program via TCP/IP. It could actually
show the Felix text or C++ text or both executing.
Note these are just ideas! not implemented yet.

Diagnostics like this are not side effects. :-)
The do not impact the program operation.
Now you are glad Felix does not enforce the rule that functions
must not have side effects.

You have to test your code on small examples first.
Something fishy MIGHT happen. In any language. Compilers are not immune to bugs
