Fallthrough in 'switch' statement
Reports fallthrough in switch statements. While occasionally useful, fallthrough is often unintended, and may lead to surprising bugs.
Example:
switch(n) {
case 1:
print 1
case 2: // "case 1" fallthrough to "case 2". Statements from "case 2" will be executed immediately after "case 1".
print 2
break
default:
print "Default"
}
