Scheme doesn't distinguish uppercase and lowercase forms of a letter except within character and string constants; in other words, Scheme is case-insensitive. For example, `Foo' is the same identifier as `FOO', and `#x1AB' is the same number as `#X1ab'. But `#\a' and `#\A' are different characters.
