I've recently been reminded how much I hate the fact that C got the precedence for the bit-wise operators completely wrong (something which I believe at least one of Kernighan and Ritchie have publicly admitted to).

I know I'm way past the Perl 6 RFC process and this isn't the Perl 6 discussion list. But I wanted to throw this out here first...

Wouldn't it be great if Perl 6 were to fix this brain damage that has plagued (well, a somewhat minor plague) C, C++, Perl 4, and now Perl 5?

Here is how I'd prefer to have operator precedence table in Perl (note that I'm listing only Perl 5 operators even though I know these change will never make it into Perl 5):

AssociativityOldNew
left terms, (leftward) list ops terms, (leftward) list ops
left -> ->
nonassoc ++ -- ++ --
right ** **
right ! ~ \ unary + and -~ \ unary + and -
left =~ !~ =~ !~
left * / % x * / % x
left + - . + - .
left << >> << >>
left (n/a) &
left (n/a) | ^
nonassoc named unary ops named unary ops
nonassoc < > <= >= lt gt le ge < > <= >= lt gt le ge
nonassoc == != <=> eq ne cmp == != <=> eq ne cmp
left & (n/a)
left | ^ (n/a)
right (n/a) !
left && &&
left || ||
nonassoc .. ... .. ...
right ?: ?:
right = += -= *= etc. = += -= *= etc.
left , => , =>
nonassoc (rightward) list ops (rightward) list ops
right not not
left and and
left or xor or xor

This preserves the relationship between the operators that you might already be mixing together, but removes the major breakedness of, for example, == binding tighter than &, |, and ^ so that you could finally just say: if(   0 == $mask & $value  ) {
