More programming-like DSL for rules and names

[neongreen]

There should be some sort of loop, for instance, which would replace zip and also let us add notes like this

latin ‘n’ [rot13'd ‘a’]
latin ‘o’ [rot13'd ‘b’]
latin ‘p’ [rot13'd ‘c’]

instead of a single note per rule.

It should work for names, too, because otherwise there are giant things like

à = ‘A’ with tilde
Ñ = ‘N’ with tilde
Õ = ‘O’ with tilde
ã = ‘a’ with tilde
ñ = ‘n’ with tilde
õ = ‘o’ with tilde
Ĩ = ‘I’ with tilde
ĩ = ‘i’ with tilde
Ũ = ‘U’ with tilde
ũ = ‘u’ with tilde
Ẽ = ‘E’ with tilde
ẽ = ‘e’ with tilde
Ỹ = ‘Y’ with tilde
ỹ = ‘y’ with tilde
Ṽ = ‘V’ with tilde
ṽ = ‘v’ with tilde

And the whole thing just should be more programming-like, period. The current syntax is only good for people who spend all the time adding rules and so need the most optimised thing ever.
