Previously we remembered the whole history of commands and replayed them on every :load/:reload, which lead to some non-linear performance characteristics (#5317). The handling of the implicit Prelude import and the implicit imports of recently loaded modules was also complicated and wrong in various obscure ways. The Prelude import works just like the implicit Prelude import in a Haskell module: it can be overriden with an explicit Prelude import. I have added a new ":show imports" command to show which imports are currently in force. Prelude> :show imports import Prelude -- implicit Prelude> import Prelude () Prelude> :show imports import Prelude () Prelude> map <interactive>:0:1: Not in scope: `map' Prelude> Full documentation in the User's Guide. There are various other little tweaks and improvements, such as when a module is imported with 'as', we now show the 'as' name in the prompt rather than the original name.
