Description

This issue was raised in the mailing list: https://groups.google.com/forum/#!topic/julia-users/iBydnBqQgxg

Although we can define a custom type and specialize the < operator for it, sometimes we may be interested in testing different operators on the spot. What are your thoughts on an additional option a la C++?

findmin(array, lt=<)
