For instance, breakSubstring is descriptive, and it's consistent with bytestring, but it's much longer than break, even though breaking on a fixed string is more common. In this case, length and frequency of use trump the other considerations in my mind.

FWIW, I take almost exactly the opposite approach with vector. I try to follow the list/array interface as closely as possible even in the presence of more frequently used but subtly different operations. My rationale is that typing a few extra characters is vastly preferable to having to search through the docs to find out what this particular library calls this particular function.

I also think breakSubstring would be an unfortunate name because (a) it's too long and (b) other collection-oriented libraries can't use this name for this operation if they don't operate on strings. How about breakSub or breakOn or something like that.
