I'm sorry if I didn't mention it, or didn't make it clear enough - it's
all about layering.

On level 0, you treat strings verbatim, and can write some subset of
apps (my point is that even this level allows to write lot enough
apps). Let's call this set A0.

On level 1, you accept that there's some universal enough conventions
for some chars, like space or newline. And you can write set of
apps A1 > A0.
