seq -package:tasty
The value of
seq a b is bottom if
a is
bottom, and otherwise equal to
b. In other words, it
evaluates the first argument
a to weak head normal form
(WHNF).
seq is usually introduced to improve performance by
avoiding unneeded laziness.
A note on evaluation order: the expression
seq a b
does
not guarantee that
a will be evaluated before
b. The only guarantee given by
seq is that the both
a and
b will be evaluated before
seq returns
a value. In particular, this means that
b may be evaluated
before
a. If you need to guarantee a specific order of
evaluation, you must use the function
pseq from the
"parallel" package.

Various utilities for forcing Core structures
It can often be useful to force various parts of the AST. This module
provides a number of seq-like functions to accomplish this.
Evaluate something. This is used to support :force in GHCi.
Sequential strategies provide ways to compositionally specify the
degree of evaluation of a data type between the extremes of no
evaluation and full evaluation. Sequential strategies may be viewed as
complimentary to the parallel ones (see module
Control.Parallel.Strategies).
