I suggest to add a trait that returns a tuple of all the functions called by a
given function, including run-time functions.


void foo() {}
void bar() {}
void spam() { foo(); bar(); }

is(__traits(calledFunctions, spam) == TypeTuple!(foo, bar))

This is useful to implement in user code transitive function properties tagged
with UDAs.

Optionally this trait too can be handy:

__traits(isRuntimeFunction, f)
