Hum, what about brackets without any prefix character at all?

Vector[int, 2] foo;

int[3] a = [1, 2, 3]; // array literal here
int[int] map;

I had similar idea. I wondered, will it be nice to allow intermixing of template parameters with function parameters... It obviously conflicts with array literals :) //Range overlap(Range)(Range r1, Range r2); Range overlap([Range], Range r1, Range r2); //template reduce(F...) template reduce([F...]) int[] arr = [ 1, 2, 3, 4, 5 ]; // Sum all elements //auto sum = reduce!("a + b")(0, arr); auto sum = reduce(["a + b"], 0, arr); auto sum = reduce(0, arr, ["a + b"]); // Compute the maximum of all elements //auto largest = reduce!(max)(arr[0], arr[1 .. \$]); auto largest = reduce([max], arr[0], arr[1 .. \$]); double[] a = [ 3.0, 4, 7, 11, 3, 2, 5 ]; // Compute minimum and maximum in one pass //auto r = reduce!(min, max)(double.max, -double.max, a); auto r = reduce([min], [max], double.max, -double.max, a); //size_t count(alias pred = "a == b", Range, E)(Range r, E value); size_t count([alias pred = "a == b"], [Range] r, [E] value); //haa? Range eliminate(alias pred = "a == b", SwapStrategy ss = SwapStrategy.semistable, Range, Value)(Range r, Value v) { alias Iterator!(Range) It; bool comp(typeof(*It) a) { return !binaryFun!(pred)(a, v); } static void assignIterB(It a, It b) { *a = *b; } return range(begin(r), partition!(comp, ss, assignIterB, Range)(r)); } Range eliminate([alias pred = "a == b"], [SwapStrategy ss = SwapStrategy.semistable], [Range] r, [Value] v) { alias Iterator([Range]) It; bool comp(typeof(*It) a) { return !binaryFun([pred], a, v); } static void assignIterB(It a, It b) { *a = *b; } return range(begin(r), partition([comp], [ss], [assignIterB], r)); }
