IRB: What was that method that greps again?

Giles Bowkett continually improves his .irbc file, and I’ve borrowed a few of those tricks. His latest is grep_methods, a helper to search for the methods available on an object. This is a very useful construct, but, as so often happens, there’s a better way baked in.

"my_arbitrary_string".methods.grep /ch/
=> ["each_byte", "match", "chomp!", "chop", "each_with_index", "chomp", "each_line", "each", "chop!"]
