depends on context.
in the perldoc pages (ie perldoc perlfuncs) you will see for sort:
sort SUBNAME LIST
sort BLOCK LIST
sort LIST
and sometimes you see EXPR
BLOCK usually has { } around it, but for sort you have an expression
followed by a comma to be shorter written.
EXPR doesn't, it just test for true or false most of the time.
PS. Please excuse me while I fall asleep. Everything I have written is in a
semi-dream-like state.
