Those single quotes are part of what needs to be matched. So the
file needs to end with "'.foo'", not just ".foo". Also, you need
to escape the ., since that is a special regex char. I think
you might want:
m/\.foo$/
Also, if the file has to end with .foo, why bother checking
for . and .., since those don't end with .foo?
Couldn't you just say:
push @my_array, $_ if /\.foo$/;
Or am I misunderstanding what you're trying to do?

(You're missing a right-paren here.)
