It depends how much you mean "like" :).  Usually whatever you would solve
using a while loop in an imperative language is solved with recursion in
Haskell.

The problem with directly having 'while' is that such a statement
depends necessarily on mutable variables (otherwise, if the condition is
'true' at the start, it will never be 'false').  Moreover, there isn't
usually a return value associated with a while statement.
