I've been batting this sort of thing around for a compiler (not perl) and like Zaxo says, it translates into an "assign" operation. In more detail, it becomes:

left-value operator expression

[download]

which roughly translates into a conceptual function like assign(left-value, eval(expression)). As to assigning relationships, the parser builds a tree. I'm not familiar with perl's tree, but it would probably look a little like this:

     =
    / \
   x   1

That is, the '=' is the important parent and the x and the 1 are arguements to it.

Is that what you were looking for?
