Idris.CaseSplit

Description

Given a pattern clause and a variable n, elaborate the clause and find the type of n.

Make new pattern clauses by replacing n with all the possibly constructors applied to '_', and replacing all other variables with '_' in order to resolve other dependencies.

Finally, merge the generated patterns with the original, by matching. Always take the "more specific" argument when there is a discrepancy, i.e. names over '_', patterns over names, etc.
