Parsley.Internal.Frontend.Analysis.Cut

Description

Exposes a transformation that annotates the parts of the grammar where cuts occur: these are places where backtracking is not allowed to occur. This information is used to help with correct allocation of coins used for Parsley.Internal.Backend.Analysis.Coins: the combinator tree has access to scoping information lost in the machine.

Since: 1.5.0.0
