Debugging in D is a lot of fun :)

I am searching for an idea, how to insert and remove trace statements quickly.

Is there a trick i can do something like this:

TRC;
TRC; void func(){
TRC;   callThis();
TRC;   foreach( ....)...
TRC; }
TRC;

Add a very short 'something' at the start of each line. This something shall do nothing, if not within any function/method, but if in executable code, it shall print the line number.

Certainly it should not change control flow.

TRC;
TRC; if( condition())
TRC;   doAction();
TRC;

Is something like this possible?

besides the fact that there might be a way to do this, it seems to me,
it's just a cumbersome substitute for simple stepping - a debugger's
job. mere stepping through D code isn't a problem with existing debuggers.
