problem also exists in 2.6. It's a, in my humble opinion, release blocker. |

It's been this way since 2.4 at least, probably earlier.

I'm not sure what release it would be blocking. The oldest version I have on hand is 2.4, and it's a problem there. If it hasn't caused an actual problem in that long, then I don't see it as all that critical. |

I believe this is actually correct. not does not bind its operand as powerfully as + does. Thus the parser sees (1 + not) x, which is quite correctly a syntax error. |
