That could be part of the problem: failwith is not ``special'' nor is ^,
hence the regular treatment of f x ^ y as (f x) ^ y and failwith x ^ y
as (failwith x) ^ y.
Operator precedence in Caml has been carefully crafted, you should
have a look at the programming guide lines that gives some hints on the
internal logics of some parts of the parsing, in the section
When to use parentheses within an expression
