Re^4: Looking for discussions of "block after or" syntax error

> Besides, as far as I understand it (but I may be wrong on that, I haven't investigated very far), it seems to me that it is not really a issue of precedence between the operators, but a simpler question of left to right

Well, you are not "knowing" you are "guessing"...

... and that's not a good base for designing code.

What's worse, I also guessed that and and or have the same precedence ...

... but now take a look what B::Deparse says:

  DB<102> dp $a and $b or $c
{
    $c unless $a and $b;
}
  DB<103> dp $a or $b and $c
{
    $b and $c unless $a;
}

too many surprises for my taste. =)
