@switch()

The @switch() statement is used to test a group of strings, to see if 
any of the matches a specified string. A different output will occur,
depending on which string from the group matched the specified one.
For example, the code:

@switch("%s", "she", "It's a girl.", "he", "It's a boy.", "What is it?")

will produce "It's a girl." if "%s" is "she". It'll produce "It's a boy."
if "%s" is "he", and "What is it?" if "%s" is neither "he" nor "she".

If you want several strings to each produce the same output if matched,
the enclosed them as a list inside of {}:

@switch("%0", {"foo", "bar"}, "You typed foo or bar.", "You didn't type
  foo or bar.")
