c++ - C++11 Avoiding Redundant Return Type in specific Situation -

-

ok, has looked @ this. i've recreated exact scenario easy viewing @ link below, i'll comment out original text had wasn't clear. http://cpp.sh/5lp4l

in comment section show calling make_some(32, std::string{"hi"}) without specifying data type declaration call. realize seems insane , way above expected use case, automatically inferring composite type (inferring wanted data, based on int/string) based on arguments wasn't necessary, or idea.

the compiler right. there's no relation given between t , args. hence, cannot determine queryresult<t> means.

what apparently expect return type of somefn forces t int, int. that's not possible 2 reasons: t denotes single type, , there's no mechanism return statement somehow affects template instantiation of make_some.

routes - Laravel 4 Wildcard Routing to Different Controllers -

-
realizing i'm going take beating this, have several questions "best practices" when constructing laravel route. do laravel routes run "first come first serve" top bottom? if route found, pass control controller (or perform action) , terminate? i have part of application acts url shortner. so, route looks this: route::get('/{id}', array('as' => 'home.text', 'uses' => 'homecontroller@text'), function($id){ //make sure id exists before pushing controller. if (storage::where('shortcode','=', $id)->count() > 0) { // route found } }); how can improved? one, i'm not sure how pass processing on controller conditionally.. sort of controller::make() ..? 3) there better way in laravel check if record exists versus doing mode::where('column','=','value')->count() 4) have legacy urls http://url.com/?...
