Because character ^ is legal in operators, how can I decide what is meaning of "^ 0."? Is it "return with value 0" or "send message #^ to self with argument 0"? Analogic situation is with character '|' (pipe).
Yes, there is a solution (^0 is always "return with zero", if I want to send #^ with zero, I have to use "self ^ 0"), but it is at least very ugly thing.

In section 2.4.5 of the Self 4.0 Programmer's Reference Manual it says: ---- An operator consists of a sequence of one or more of the following characters:
! @ # $ % ^ & * - + = ~ / ? < > , ; | ` \
Two sequences are reserved and are not operators:
| ^
Productions [snip]
Examples: + - && || <-> % # @ ^ ----
Odd... the last example is what you want and we were told explicitly it wasn't an operator (binary selector). This is from an old version of the manual - I wonder if it was a typo.
