Status: RESOLVED DUPLICATE of bug 1126813

(Developer Infrastructure :: Source Code Analysis, defect)

Description

[Jeff Muizelaar [:jrmuizel]]

class LargeClass {
...
}

vector<LargeClass> list;

we want to do detect:

for (auto l : list) {
   ...
}

and suggest:

for (const auto l& : list) {
   ...
}

----

This maybe be tricky to get right and avoid any false positives.
