Word description
Parses Factor source code from a string, and calls the resulting quotation, which must have the given stack effect.

Notes
The code string is parsed and called in a new dynamic scope with an initial vocabulary search path consisting of just the syntax vocabulary. The evaluated code can use Syntax to control word lookup to alter the search path.

Errors
Throws an error if the input is malformed, or if the evaluation itself throws an error.
