.. _monomorphism:
Switching off the Monomorphism Restriction
------------------------------------------
.. extension:: NoMonomorphismRestriction
:shortdesc: Disable the monomorphism restriction.
:default: on
:since: 6.8.1
Prevents the compiler from applying the monomorphism restriction to
bindings lacking explicit type signatures.
Haskell's monomorphism restriction (see `Section
4.5.5 <http://www.haskell.org/onlinereport/decls.html#sect4.5.5>`__ of
the Haskell Report) can be completely switched off by
:extension:`NoMonomorphismRestriction`. Since GHC 7.8.1, the monomorphism
restriction is switched off by default in GHCi's interactive options
(see :ref:`ghci-interactive-options`).
