It's not terrible, but it's far from being nice. Strings are sharp and rough
tools, when used for such purposes.
Map and filter of Phobos2 are lazy only, so if you need an array you have to
add another function call (that's named array() in my dlibs, I don't remember
the Phobos2 name).

In Phobos2 it's named iota (from APL, maybe), it doesn't require the
exclamation mark (bang, !) (but it's not smart enough yet to accept just one
argument, and default the first one to zero).
