Diamond operator has several issues

[snoopyjc]

Diamond operator with glob expression generates bad code. For example:

while(<*.c>) ...

Empty diamond operator <> is supposed to read all the files from @ARGV, but instead only reads STDIN.

Double diamond operator <<>> is supposed to be a safe version of <> but doesn't work.

A scalar in a diamond operator <$var> should read from that file handle.
