Subject: RegExp to string

I have been using a simple regexp match to find is a string contains another
string.  This has been working fine until the matched string contained a
regexp character.

I wonder if the code in string =~ should do a Regexp.escape if the incomming
expression is a string?

Example

irb(main):039:0> x = "jane and tarzan"
"jane and tarzan"
irb(main):040:0> y = "tarzan"
"tarzan"
irb(main):041:0> z = "tarzan ("
"tarzan ("
irb(main):042:0> x=~y
9
irb(main):043:0> x=~z
RegexpError: premature end of regular expression: /tarzan (/
        from (irb):43:in `=~'
        from (irb):43
irb(main):044:0>
