Description

See listing below, showing behavior with ruby and with jruby. With ruby 1.9.2 both ways of printing the number of characters in "1024" produces "4", while with jruby the expression is parsed differently and the resulting difference in precedence produces two answers ("4" and "1024").

The --1.9 mode was not in effect during the test. Using 1.9 mode, the results are correct (they agree with MRI ruby 1.9.2).
