As you can see, it is not wise to use operator names for constants.

    ... it is not wise to use operator names for constants.

    ceo: ... or for functions, which is what constants are: 

    >perl -wMstrict -le
"sub tr  (&$) { $_[0]->($_[1]) }
 sub trx (&$) { $_[0]->($_[1]) }
 ;;
 $_ = 'foo';
 print 'A: ', tr{ print qq{tr match: $_[0]} }/foo/;
 print 'B: ', trx{ print qq{trx match: $_[0]} }/foo/;
"
A: 0
trx match: 1
B: 1
