coexist inside brackets:
	type t = ['dt' | 'a]
is supposed to be a valid type, but for now the new syntax isn't working inside
brackets, so to write this type use:
	type t = ['dt' | `$a]

Last problem (hopefully) is that characters inside simple quotes are not stored
properly by the lexer.

if it is a string or a type variable in the parser. Still some errors in the
parser (see make test).

At this point, the lexer gives a type if it sees a "'" then IDENT then ' '.
This is not enough, but now simple tests like this one works:
	fun ('A -> Int) _ -> 0
