Sometimes during profiling a program becomes too much slow. To improve this I
suggest to add an annotation to disable profiling for a specific function that
the programmer knows to be slow.

The profiler will not trace foo() and all static/instance member functions of
Bar/Spam:

pragma(notrace) void foo() { /*...*/ }
pragma(notrace) class Bar { /*...*/ }
pragma(notrace) struct Spam { /*...*/ }

-------------

Similarly, I'd also like some way to disable the tracing of a
function/class/struct/union coming from another module. This syntax is not good
yet:

import foo: pragma(notrace) something;
