I don't think anybody's come up with a candidate keyword that reads well in most/all situations. Consider:

make accepts(int, (int, float)) make returns(int) def foo(arg1, arg2): return arg1 * arg2

 make accepts(int, (int, float)):
     make returns(int):
         def foo(arg1, arg2):
             return arg1 * arg2

looks more like Python to me. And I know it's nested, but it reads better IMO.

Aren't we really trying to recreate def as a multi-line lambda that binds when it's in a context that is not expecting a function argument in block form? One way of looking at def or any of the other keywords that introduce blocks is as operators that take block(s) as argument(s).
