updateEps :: (ExternalPackageState -> (ExternalPackageState, a)) -> TcRnIf gbl lcl aSource

Update the external package state. Returns the second result of the modifier function.

This is an atomic operation and forces evaluation of the modified EPS in order to avoid space leaks.

updateEps_ :: (ExternalPackageState -> ExternalPackageState) -> TcRnIf gbl lcl ()Source

Update the external package state.

This is an atomic operation and forces evaluation of the modified EPS in order to avoid space leaks.
