Pattern: Use of caller[n]
instead of caller(n..n).first
Issue: -
This rule identifies places where caller[n]
can be replaced by caller(n..n).first
.
# bad
caller[1]
caller.first
caller_locations[1]
caller_locations.first
# good
caller(2..2).first
caller(1..1).first
caller_locations(2..2).first
caller_locations(1..1).first
