valuesplitHsApps :: HsExpr GhcRn -> TcM (HsExpr GhcRn, [HsExprArg 'TcpRn])

Split the expression into an application chain See Note [splitHsApps] See Note [Application chains and heads]

valuerebuildHsApps

:: HsExpr GhcTc
the function being applied
-> [HsExprArg 'TcpTc]
the arguments to the function
-> HsExpr GhcTc

Rebuild an application: takes a type-checked application head expression together with arguments in the form of typechecked HsExprArgs and returns a typechecked application of the head to the arguments.

Variant of getDeepSubsumptionFlag which enables a top-level subsumption in order to implement the plan of Note [Typechecking data constructors].
