Constant Summary

MATCH_OVERLOAD_MACRO = " methods.select { |m| m.name.stringify == sig[1] && !m.annotation(BindgenWrapper) }.each do |m|\n args = m.splat_index ? m.args[0...m.splat_index] : m.args\n ok = sig[2].size >= args.select { |a| a.default_value.is_a?(Nop) }.size && (m.splat_index || sig[2].size <= args.size)\n sig[2].each_with_index do |name, i|\n r = ok ?

Macro code adding the mangled name sig[0] to forwarded if any method in methods named sig[1] accepts the argument types sig[2]. Unresolvable type restrictions are assumed to match.
