#7253: Top-level bindings in ghci -------------------------------------+------------------------------------- Reporter: Feuerbach | Owner: Type: feature request | Status: new Priority: normal | Milestone: 8.0.1 Component: GHCi | Version: 7.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): parsing.
