The eval vocabulary implements support for evaluating strings of code dynamically.

The main entry point is a parsing word, which wraps a library word:
eval(

eval ( str effect -- )


This pairing is analogous to that of call( with call-effect.

Evaluating strings with a different vocabulary search path
eval>string ( str -- output )
