    #$ ruby -w parserbug.rb 

    #lexerbug.rb:1: warning: `+' after local variable is interpreted as binary operator

    #lexerbug.rb:1: warning: even though it seems like unary operator

    # Bug 1: what local variable?

    # Bug 2: there is no ambiguity in the syntax so the warning is a parser bug

    puts '' +''
