mang.d(10): Error: function core.stdc.stdio.fgetc (_iobuf* stream) does not
match parameter types (File)
mang.d(10): Error: cannot implicitly convert expression (stdin) of type File to
_iobuf*
mang.d(19): Error: function std.demangle.demangle (immutable(char)[] name) does
not match parameter types (char[])
mang.d(19): Error: cannot implicitly convert expression (buffer) of type char[]
to immutable(char)[]

The former can be solved by importing std.c.stdio and using std.c.stdio.stdin
in the call to fgetc.

The latter problem is probably best resolved by having demangle take a
const(char)[] rather than a string; otherwise the example program does a *lot*
more allocation.

And while we're at it, we could use a keyword for documentation.
