To answer your actual question: Ruby considers ! and ? parts of
identifiers only in method names, and only when the name ends with one
such a character.
The names of local variables, as well as instance and global ones, can't
use ? and !. We may want to handle this eventually:
irb(main):001:0> @abc?1:2
=> 2
irb(main):002:0> abc = 1
=> 1
irb(main):003:0> abc?2:3
SyntaxError: (irb):3: syntax error, unexpected ':', expecting $end
