ForExpr is a nonkernel node which executes code for each element in a collection or other object implementing iterate/1.

"for" (optKeyPattern "=>")? valuePattern "in" collection "{" body "}" ({optBreakCatch an EMatcher}: "catch" pattern "{" expr "}")?

XXX We need to formalize the grammar definitions used in our spec

Fields

• optKeyPattern :nullOk[Pattern]
• valuePattern :Pattern
• collection :nullOk[EExpr]
• body :EExpr
• optBreakCatch :nullOk[EMatcher]

Expansion

XXX Define the expansion of ForExpr

Kudos! What a neat way of thnkiing about it.
