Unlike cling, drepl doesn't seem to support overloading:

Welcome to D REPL.

std

bar
D> void bar(int) { writeln("int"); }
bar
D> bar(42)
`_mod2.bar` at /tmp/drepl.adse9Q/_mod2.d(3) conflicts with 
`_mod1.bar` at /tmp/drepl.adse9Q/_mod1.d(3)
template `std.stdio.write` cannot deduce function from argument 
types `!()(void)`, candidates are:
/usr/include/dmd/phobos/std/stdio.d(3669):        
`std.stdio.write(T...)(T args) if (!is(T[0] : File))`

It can envision the implementation that produces that result, and 
in terms of that implementation it makes sense, but ouch, that's 
not user friendly or in-line with regular D semantics.
