("toe" just doesn't sound good)Tail has a history of being used to mean "everything but head" in functional programming languages like Haskel and ML. So of back, last, end, tail, rear, foot, toe, it seems every one has some strike against it. back - could be mistaken for an action last - doesn't pair well with "head", and "first" sounds too much like item #1 overall end - in C++ usually means "one past the end" tail - in FP langs means "everything but head" rear - makes Walter thing unhappy thoughts toe - sounds silly, doesn't make so much sense for a range that represents a tree structure. Toe is sounding pretty ok. Actually I think the critique that it doesn't make sense for a non-linear range should be thrown out. Linearizing is the whole purpose of a range. So even if it wasn't linear before, a range effective is providing a linearized view of it. So that leaves "it sounds silly", which is a pretty weak subjective argument against. --bb
I disagree with the above reasoning. "Language X has different meaning for word Y" is not a valid argument IMO. One of D's stated goals is to break backward compatability when needed in order to get a better language design, yet we constantly keep getting back to " but in C++ ...". if people want to use a backward compatible language they already have C++ for that, and they don't need D. I for one, prefer to change when the change makes sense and brings more clarity. Yes, it'll be initially confusing for former C++ programmers, but IMO it's worth it in the long run. head/toe is not just silly, it's also non intuitive for non-English speakers. (I'd be confused by this, had i seen this for the first time) When I write D code I think in D, not any other language and I'm sure that applies to most people. making the switch to "D mode" is easier IMO than trying to remember confusing terms, just because some other language has slightly different meaning for the deafult terms.
Hack, I don't even know haskel, why should I care about haskell's definitions?
I already asked in a previous post - would a chinese programmer intuitivly think that toe is the last item in a range?
