Class: RuboCop::Cop::Lint::EnsureReturn
Overview
Checks for return
from an ensure
block.
return
from an ensure block is a dangerous code smell as it
will take precedence over any exception being raised,
and the exception will be silently thrown away as if it were rescued.
If you want to rescue some (or all) exceptions, best to do it explicitly
