It is easy to align the parser with D syntax. Anyway, syntax is not the problem here, and the implementation can be downgraded to not support parsing and/or proper names at any point.I fail to see how no parens after log or "^" in lieu "^^" would make a positive difference.
Neither have I attempted to show anything like that. All arguments in this debate are obvious and boring, so no need to discuss it.
What would be a few examples of things that won't work pleasantly enough? ...
You gave this example: http://en.cppreference.com/w/cpp/container/forward_list/insert_after 1-2) BigO("1") 3) BigO("count") 4) BigO("distance(first,last)") 5) BigO("ilist.size()") There's also this: On 12/06/2015 12:55 AM, Andrei Alexandrescu wrote:
Well you'd need multiple terms if you want to say things like, "inserting a range into an array is O(array[].walkLength + r.walkLength)." When you insert a range in a binary search tree, the complexity would be O(log(array[].walkLength) * r.walkLength).
BigO("array[].walkLength + r.walkLength");
BigO("log(array[].walkLength) * r.walkLength");
