qstring-ref

Finds places where QString::fooRef() should be used instead of QString::foo(), to avoid temporary heap allocations.

Example

str.mid(5).toInt(ok) // BAD

str.midRef(5).toInt(ok) // GOOD

Where mid can be any of: mid, left, right. And toInt() can be any of: compare, contains, count, startsWith, endsWith, indexOf, isEmpty, isNull, lastIndexOf, length, size, to*, trimmed
