Instance Method Detail
Inside a comma-separated list of parameters or args, this becomes true and
the outermost pair of parentheses are removed from type restrictions that
are ProcNotation nodes, so foo(x : (T, U -> V), W) becomes
foo(x : T, U -> V, W). This is used by defs, lib funs, and calls to deal
with the parsing rules for ->. See #11966 and #14216 for more details.
