  * resolution:  = fixed
  * status:  new = closed

Comment:

 Done; to disable the printing behaviour for bindings, use
 {{{
 :set -fno-print-bind-result
 }}}
 in GHCi (or -fno-print-bind-result on the command line).

Comment (by simonpj):

 We changed it because a lot of the time it's very convenenient to see the
 result of an action.  But you have a good point.

 (As an unsatisfactory workaround, you could wrap x an un-Showable
 constructor, or in a function; but that changes its type.)

 What do others think?  Return to old behaviour?  Have another settable
 option?  Or what?

I was thinking about this a bit.

Ideally we'd have:
:set verbose
:unset verbose

or similarly, to switch between the two behaviours.

Comment (by duncan):

 Would it be possible to distinguish based on the syntax?

 {{{
 content - getContents
 }}}

 would not print anything, but

 {{{
 getContents
 }}}

 would print. That seems reasonably intuitive to me.

Apparently, ghci has changed its behaviour from 6.4 to print the result of
 IO actions, even if assinged to a variable.  I often do something like


 {{{
 ghci x - myParser largeFile
 }}}


 in order to do various tests on x.  Having the contents of x dumped to the
 monitor is annoying,
 and defeats laziness testing completely.
