#3452: Show type of most recent expression in GHCi
-----------------------------+----------------------------------------------
Reporter: ozy | Owner:
Type: feature request | Status: new
Priority: normal | Component: GHCi
Version: 6.10.4 | Severity: normal
Keywords: | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
Currently, any expression resulting in a value with no `Show` instance
results in an error message. This is confusing for new users (especially
if they don't yet understand typeclasses) and overly verbose for
experienced users. Instead, the REPL should simply display the type of the
expression, as if the user had used `:t`.
