Hi,

|String#tr(search, replace [, flags]) where flags can be COMPLEMENT and SQUEEZE

When I designed String#tr, first I thought of

  String#tr(search, replace [, flag]) where flag is for true/false to squeeze

Then I changed my mind because mere boolean flags would make programs
harder to read.

But in the future, after keyword argument is intoduced (maybe in 1.7),
there can be keyword options for String#tr, e.g.

  String#tr(search, replace, squeeze: true, complement: false)

Hmm, it's possible.  It remainds me Common Lisp very much though.
