If the EqRel is ReprEq, makes a SubCo; otherwise, does nothing. Note that the input coercion should always be nominal.

isTcReflexiveCo :: TcCoercion -> Bool Source #

This version does a slow check, calculating the related types and seeing if they are equal.

unwrapIP :: Type -> CoercionR Source #

Create a Expr that unwraps an implicit-parameter or overloaded-label dictionary to expose the underlying value. We expect the Expr to have the form `IP sym ty` or `IsLabel sym ty`, and return a Expr `co :: IP sym ty ~ ty` or `co :: IsLabel sym ty ~ Proxy# sym -> ty`. See also Note [Type-checking overloaded labels] in TcExpr.

wrapIP :: Type -> CoercionR Source #

Create a Expr that wraps a value in an implicit-parameter dictionary. See unwrapIP.
