Then it will be Wrong. This decision is pretty much set in stone.
As I say in Exegesis 3: Think of it as the dot operator under extreme
acceleration.

With user-definable operators you can use any Unicode sequence as a string:
my sub operator:cc is prec(\&operator:_($$)) ($x, $y) { $x _ $y }
my sub operator:cat is prec(\&operator:_($$)) ($x, $y) { $x _ $y }
my sub operator:\N{CIRCLED PLUS}
is prec(\&operator:_($$)) ($x, $y) { $x _ $y }
etc.
