I'm confused by why you might be confused by this. opEquals by
default is simply a bit-level value check.
"x" and "x".idup are two different things.
"x" might be:
ptr = 0xDEADBEEF
length = 1
and "x".idup might be:
ptr = 0xDEADBEEE
length = 1
Clearly they are not equal. If you have a particular definition
that isn't the same as the the bit-level basic equality, you have
a method of defining it.
For why the compiler treats them the same... well, it simply
doesn't create a new place for "x".idup. Simple optimization that
doesn't matter unless you're comparing their identity.
