GHC.Tc.Zonk.Monad

Description

The ZonkM monad, a stripped down TcM, used when zonking within the typechecker in GHC.Tc.Zonk.TcType.

See Note [Module structure for zonking] in GHC.Tc.Zonk.Type.

Synopsis

The ZonkM monad, a stripped down TcM for zonking

data ZonkM a where Source #

A stripped down version of TcM which is sufficient for zonking types.
