Imp.Signature.ParseError exception (Imp v0.5.0)

Raised when a signature string cannot be parsed.

Imp.Signature.new/2, and every constructor that takes a signature string, raises it. :input is the string as given and :position the offset where parsing stopped. The message quotes the input, points at that position, and suggests a spelling when the mistake is a near miss, such as a misspelled type.
