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.
I know, that is why I have not implemented this yet. Basically it should
be possible to implicitly pass a whole scope to a template, or at least,
to have local templates.
Example:
auto foo(Range)(int n, Range r) {
return compr!q{x * n; x <- arr, log(x), x*x > 4};
}
Workaround:
auto foo(Range)(int n, Range r) {
mixin Compr!q{x * n ; x <- arr, log(x), x*x > 4};
return compr;
}
but
auto foo(Range)(int n, Range r) {
return mixin(compr!q{x * n ; x <- arr, log(x), x*x > 4});
}
is clearly better.
