Are you proposing that == behaves as STREQUAL, or as EQUAL?

What's the difference?

Okay, for <, >, there is an obvious answer, but for ==, I am trying and failing to think of a situation where treating the arguments as numbers would give a different result vs. treating them as strings.

given that I already know how these things work with if(VARIABLE
constructs, I would expect that same thing from this new syntax.
i.e. if(VAR == 5) works just like if(${VAR} == 5)

This I think I would expect also. What I would expect to be different from STREQUAL is that 'if("${var}" ==' is NOT the same as 'if(${var} =='.

- it doesn't need a policy, existing behaviour doesn't change

Agreed. (Unless you still expect the if(VAR behavior as you have with the other 
operators.)

On the other hand, I would probably be in favor of a policy to inhibit automatic variable expansion of a quoted string... and of making "don't do that" the default behavior, as it is hard to imagine when the current behavior would *ever* be desired.
