I thought the syntax was incorrect....
"cat" =~ "a" #=> 1
Fails as it's looking to match a reg ex not a string.
Should be:
"cat" =~ /a/ #=> 1
Or am I wrong?!?!

Indeed, the example *is* wrong (judged by current ruby). However the
documentation states that:
str =~ obj => fixnum or nil
Match—<snip> If obj is a String, look for it in str (similar to
String#index). Returns the position the match starts, or nil if there
is no match. Otherwise, invokes obj.=~, passing str as an argument.
The default =~ in Object returns false.
"cat o' 9 tails" =~ '\d' #=> nil
<snip>
(http://ruby-doc.org/core/classes/String.html#M001453\)
The question was why it doesn't work. The answer: the online
documentation is outdated (I don't know how the docs in the install
package look like, I haven't installed 1.8.5 yet).
