@qyriad: w-what does the ^ mean... ?
me: ... which one?

verilog's reduction operators are one of it's neater quirks (^a[3:0] is equivalent to ^'ing together all of the bits of a)
Fun fact: prefix-& is great for exposing bugs in compilers that have to do with self sized expressions. For ex: &(0?a[1:2]:a[0]) should compile to constant zero and not a[0], but some tools eagerly optimize the 0?x:y pattern, screwing up the width of the self sized expression.

would it be more obvious what the behavior should be if it were &(0 ? a[1:0] : {1‘b0, a[0]}) ?
