Fixed with the addition of ParameterIdentifierTuple
(http://dlang.org/phobos/std_traits.html#ParameterIdentifierTuple).

Well there is now __parameters, but this gives out both the types, param names,
and default values:

void test(int x, int y = 1) { }

template ParameterTuple(alias func)
{
static if(is(typeof(func) P == __parameters))
alias P ParameterTuple;
else
static assert(0);
}

void main()
{
pragma(msg, ParameterTuple!test);
}

> (int x, int y = 1)

I would personally like to wrap ParameterTypeTuple, ParameterStorageClassTuple,
and provide a single GetParameters template which would return a tuple of these
struct objects:

struct Parameter(Type, alias DefVal)
{
ParameterStorageClass stc;
Type type;
string name;
alias DefVal defaultValue;
}

It's questionable how doable this is but it would make the API easier to use.
