removing features

[gkz]

So far (on master), slated for removal (and currently with compiler notices upon use):

• short function syntax - f(x) = x - [currently has notice] why: hacky implementation, duplicating functionaly use --> to make curried functions
• +++ concat op [currently has notice] why: added ++ as concat op, which is shorter and better
• where statement - relatively useless - just use local var assignment or a let statement [currently has notice]
• undefined alias for void - added for CoffeeScript compatibility, but with coffee2ls that is not an issue [currently has notice]
• !? inexistence op [currently has notice]

---

discussion:

• choose one of ** or ^ for power op?
• remove import and importAll?
• remove x is not y to mean x isnt y, have it mean x is !y instead
• yes/no/on/off aliases - added for CoffeeScript compatibility, but now with coffee2ls, this is not an issue

More controversial:

• remove standalone use of @
• remove standalone or hanging use of ::

Match is a must have feature

[ozra]

+1 on all except stand alone @ (mostly because I have a lot of old code using it).

[dead-claudia]

@ozra I agree WRT the original list (except I also want to keep C:: == C.prototype).

@focused I agree, and I wish match was documented. It does IMHO have odd behavior with certain cases (it's rather ad-hoc in how it matches things), and could stand to be fixed, but it should still stay around.

I'm disappointed the single-item array not evaluating to an array "feature" wasn't removed in 1.5 after all. 😕 It's something that actively causes pain through unexpected behavior, rather than just duplicating behavior.
