But what's the percentage of Qt developers that understand the
subtleties between Q_FOREACH and range-for ?
Having a toolbox with two similar-but-not-quite constructs is bad for
less seasoned users.
I prefer explicitly assigning the container to a const local variable
instead of relying in the magic behind macros.

It is, see Qt's documentation:
"Since Qt 5.7, the use of this macro is discouraged. It will be
removed in a future version of Qt"
