You can already do something like that, although very hackish: turn on trace
profiling and override the prolog/epilog code from druntime (I think these are
called _trace_pro_n and _trace_epi_n, just grep the source for their syntax).
Just make *very* sure to use only naked declarations in these and any routine
they may call, or else you will just call back into _trace_pro_n until you get
a stack overflow.
