Description

The infix -> token seems to not be able to parse a list on its right hand side.

get->[a, y]

Various ppx's could interpret the -> token differently so this should probably be supported.

Research direction

Start by locating the Reason parser handling of infix -> and its parsing of right-hand-side expressions; the issue does not name a file or test. Check how get->[a, y] is currently parsed and whether parser tests cover this syntax. Done means the expression parses with a list on the right-hand side while preserving the intended handling of ->.
