AFAIK you can't get any parameter type from just-binary. The code in 
there just expects the stack to have a certain structure and fullfil 
certain consitions. If these conditions are not fullfilled it'll probaly 
segfault.
Because D (like C++ and unlike C) allows overloading the same name on 
different parameter types, this information has to be put into the name 
(mangling) to avoid name clashes for the linker.

PS: Just a thought of mine: You should be theoretically be able 
regenereate function signatures from mangled names. Maybe someone could 
such a tool.
