...the parser has an additional clue which it uses to work out the right way to parse the statement...

I think the parser is reallly straightforward in this respect: known -X filetest operators will give the error, unknown ones will give the warning. Nothing to do with upper case of lower case: -a works but gives the warning even though lowercase, whereas -T will give the compile error.

perldoc -f -X lists the following uppercase filetest operators: 

 -T  File is an ASCII text file (heuristic guess).
 -B  File is a "binary" file (opposite of -T).

 -M  Script start time minus file modification time, in days.
 -A  Same for access time.
 -C  Same for inode change time (Unix, may differ for other platforms)
so don't call your constants T, B, M, A or C ;-).
