#10160: GHCi :sprint has odd/unhelpful behavior for values defined within the REPL -------------------------------------+------------------------------------- Reporter: bitemyapp | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.8.4 Resolution: | Keywords: :sprint Operating System: Unknown/Multiple | thunk evaluation non-strictness Type of failure: Incorrect result | laziness runtime ghci repl at runtime | Architecture: Blocked By: | Unknown/Multiple Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): How about adding a sentence like this to the documentation of `:print`:
Note that literals and data constructor applications may appear as values rather than thunks even if nothing has yet forced their evaluation, since GHCi constructs these values directly in weak head normal form.
