Well, I'd expect it to be compress!lzw(), but in any case, what it buys you is
that you can pass the algorithm around without caring what it is so that while
code higher up on the stack may have to know that it's lzw, code deeper down
doesn't have to care what type of algorithm it's using. Now, whether that
flexibility is all that useful in this particular case, I don't know, but it
_does_ help with generic code. It's like how a lot of std.algorithm takes its
predicate as an alias.
There is zero utility in this:
auto compress(alias dg)
{
return dg();
}
Not even for generic code.
