==================== Summary ====================
Name: Compiler-nice.280 Author: nice Time: 24 February 2014, 10:41:41.999 pm UUID: 6e62064c-bd88-4957-98e4-c57da15738fc Ancestors: Compiler-nice.279
Accept ^ as a binary selector With this change, binary selector can be arbitrarily composed of #verticalBar | #upArrow ^ or any other Character classified as #binary (See Scanner class>>initializeTypeTable)
=============== Diff against Compiler-nice.279 ===============
So
foo | a | a := 1 + 3 ^ a.
actually means
foo | a | a := 1 + 3 ^ a. ^ self.
Which might be surprising - currently the former will fail with a sensible error message. (I say this while liking that I can write "2 ^ 2" instead of "2 squared"...)
Yep, this is the objection that I anticipated in my first annoucement. Note that the format is clearly expressing the intention, that makes me think that the Python's interpretation of formating is not that bad ;) but we ain't gonna change that...
If #'^' is not a Symbol, then you'll get a warning that you used a new selector. I don't remember, are all 1 char Symbol still interned, or did we change that? Of course, once you implement ^ as a binary message, then the code is accepted as is without any sort of warning...
It's the same for self which is interpreted as a message send in this code: x := 1 + self foo self bar: x. It warn once, at first self send, but then, #self is interned and you're never warned again...
For this sort of error, we could have a kind of lint rule for checking indentation : a single tab after a cr should match a beginning of a new statement (same with proper indentation inside blocks)

This would make sense if we we switch to ↑ (U+2191) as return.
