As with any form of communication, it takes some background knowledge
to be able to express oneself.  For example, if you don't know C
aliasing rules and violate them, you're up for surprises when the
compiler optimizes guessing you know about them.  This is really no
different.  And you don't have to reverse-engineer anything, the rules
are documented in both cases.
