Edwin Brady a2ce8d0b7d Add as patterns ... When we encounter them, not that they're a binding as normal, but also record the thing they expand to. Then bind as a PLet, and convert that to a Let on the RHS so it has computational force. The case tree compiler knows about as patterns, so they get compiled to use the appropriate name on the rhs (rather than a let).		2019-05-09 16:48:09 +01:00
