Earlier quoted context omitted.
I had a bit of a play around with it. It's pretty powerful being able to see in one line ( or possibly multi line ) It really hammers home the concept that a function is a transformation, and of what into what. And I think this syntax would probably encourage pure functions. And it's so useful to allocate the return in the top line. I really like go.
What language that has static types doesn't have the func, params, and return type in one line?
K&R C had implied type of 'int' for both arguments and return value, and didn't list the types of arguments on the line specifying function name, argument names and return type:
int foo(x,y)
{
return baz(x,y);
}
bar(x,y,z)
short x;
int z;
{
return x+y+z;
}
baz(x,y,z)
{
return 42;
}
