Oh yes.  Let's say until March 29.

Normally I use qualified imports, but these two modules are special.
Foreign must be imported unqualified when used with hsc2hs, because
hsc2hs emits unqualified identifiers.  And Control.Monad.... well, it
doesn't have to be unqualified, but since it's full of control
structures it's one of the few modules I'm accustomed to importing
unqualified.
