It's not a nice solution, but that's essentially what Python does in such
situation:
def foo(x, y, **kwds):
# here kwds is a dict of str:value
In D there are Typesafe Variadic Functions, you can use:
int sum(int[] ar ...) {
To define a function that takes an arbitrary number of ints or a dynamic array
of ints (and maybe fixed sized array of int too).
Another (weird! never used) alternative usage of the Typesafe Variadic
Functions is to build an object on the fly.
So that syntax may be extended to support:
void foo(Variant[string] kwds ...) {
}
I may show this silly idea in the main D newsgroup later today.
