Warn.hookOpCmp

int hookOpCmp(Lhs, Rhs)(Lhs lhs, Rhs rhs)

Called automatically upon a comparison for ordering using one of the operators `<`, `<=`, `>`, or `>=`. In case the comparison is erroneous (i.e. it would make a signed negative value appear greater than or equal to an unsigned positive value), then a warning message is printed to stderr.

Parameters

`lhs`	The first argument of `Checked`, e.g. `int` if the left-hand side of the operator is `Checked!int`
`rhs`	The right-hand side type involved in the operator

Returns

In all cases, returns lhs < rhs ? -1 : lhs > rhs. The result

is not autocorrected in case of an erroneous comparison.
