If statement with too many branches

Reports if statements with too many branches. Such statements may be confusing, and are often the sign of inadequate levels of design abstraction.

Example:

if (a) {
  print "foo"
} else if (b) {
  print "bar"
} else if (c) {
  print "baz"
} else if (d) {
  print "Too many branches"
}
