or, in a library:
compr!q {2 * x ; x <- iota(10), log(x), x*x > 4};
compr!q{2 * x ; x <- iota(10), log(x), x*x > 4};
The library solution has problems with scope variables. Example:
auto foo(Range)(int n, Range r) {
return compr!q{x * n; x <- arr, log(x), x*x > 4};
}
More importantly, IMO, is that the notation does not clearly
mark what is what. is that interpreted (iota(10), log(x))
or (log(x), x*x > 4)?
