-f -x -w $file
It's new language features time !
Since a few hours, you can now write with bleadperl:
-f -w -x $file
and perl acts as if it were
-x $file && -w _ && -f _
As I added in perlfunc, this is only syntax fancy : if you use the return value of -f $file as an argument to another filetest operator, no special magic will happen. If I remember correctly, Perl 6 will provide a full-fledged form of this syntax (with filehandle context and all). (To be appearing in the next p5p summary...)
-f -x -w $file

Yay! (Score:2, Interesting)
How about extending _ to mean the article passed to the previous test to apply to other tests?
if ( exists $foo->{member} and defined $foo->{member}) {}
becomes
if ( exists $foo->{member} and defined _ ) {}
It's now just a little shorter
