No. Inlining is considered an optimization, which implies that it
doesn't change the semantics except when it was not fully specified
in the first place. E.g. the order of evaluation of arguments is
unspecified, so it might be different depending on inlining; but
OCaml does specify that each argument are evaluated exactly once
and inlining doesn't change that.
