This expression:

(set-special! "$" 'interpolate)

Completely screw up the parser.

it throws an error about the unbound first letter of any name:

Unbound variable `d'

converted the string to regular expression

The problem was that the Lexer state machine was expecting:

char.match("$")

and $ was implicitly converted to a regular expression that always match.
