where to import `trace' from

[S.D.Mechveliani]

Please, what is the ghc-standard way to import `trace' function of
ghc-4.04  library ?

Someone pointed this long ago, but i cannot recall now.
.../user_guide/librarie*   has, probably, to specify this.
But why it does not ?

Thank you in advance for the help.
