I just had a crazy idea. "hijackable" keyword (yeah... another
keyword):
Given a function:
"Ret foo(T input, Args... args) @hijackable"
Then, when the compiler sees:
"foo(input, args);"
It will always forward directly to T.foo if T.foo exists,
bypassing std.foo entirely.

What about stuff like this:
import some.pkg;
some.pkg.foo(x);
Does this still call x.foo()?
In theory, yes, because "some.pkg" would *be* X.foo, or at the
very least, a very thin wrapper. You'd get the very same result
with "static if" based implementation, such as "moveFront", where
"std.range.moveFront(r)" still just calls "r.moveFront()". Ditto
for "take", which just calls opSlice.
What if 'foo' is an alias for 'bar', or vice versa?
An alias shouldn't change anything I think.
