Ruby: What's the proper syntax for a boolean regex method?

Question

What is the proper syntax for a method that checks a string for a pattern, and returns true or false if the regex matches?

Basic idea:

def has_regex?(str

As I wanted this to work generally, and not just for any specific project, I do not want to modify the environment at all.

I was able to get it to work by simply using the return value from the normal match method as a conditional. Tested both the positive and negative case on this sample string:

irb(main):014:0> if "123".match(/.2./); puts "worked"; end
worked
=> nil
irb(main):015:0> if "123".match(/.3./); puts "worked"; end
=> nil
