ah, so what this tells me is that, if i want to match a wildcard pattern
and i use the wildcard() function, there really is no effective difference
if i do that at the top of my makefile with either of:

files = $(wildcard *.o)
files := $(wildcard *.o)

if, as you say, it's the cached version that is used to evaluate these,
then in that respect they really are equivalent for what i was doing with
