Here is what I mean by commified. Consider the following
2 versions of the same map
The first form is more general, you can put more complex
logic inside the block. The second form replaces the block
with a comma and shaves a character. Often you can shave
a few characters off of someone's solution by seeing that
a few map
's or grep
's can switch over to the version
with the comma.
Sometimes it is not obvious that you can. So sometimes I
just have to try it out. As in the case:
Incidentally the following version is the same size, but
has slightly nicer (IMHO) output:
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
