Summary: Chainable template mixin Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2011-05-21 16:43:54 PDT --- I suggest to add something like this to D2 Phobos (this is D1 code): template Chainable() { Chain!(typeof(this), Range) opCat(Range)(Range r) { return chain(this, r); } } Then in the body of a lazy range both Phobos ones like map, filter, zip, iota, and so on, and user-defined ones, you may add: mixin Chainable; This allows to write more natural and readable code like: iota(5) ~ filter!q{a}([1,0,3]) map!abs([1,2,-5]) ~ [10, 20] instead of more noisy: chain(iota(5), filter!q{a}([1,0,3])) chain(map!abs([1,2,-5]), [10, 20]) See also bug 5638 for an useful optimization. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
