I think that there is a lot speaking against sloc.
First it's often (ab?)used for "Ha! My language x is better than
yours. I can write a web server in 3 lines, you need 30".
And then slocs say a lot of things about a lot of things. Like:
Experience (being new or not used to X I'll need more lines in X
than in "my" lang, say, D), built in vs. library, coding style,
and others.
In the end "100 sloc in X vs. 180 sloc in Y" quite often means
close to nothing. Putting it bluntly: If I know enough about all
the relevant details of the languages+environment to arrive at
having sloc mean anything useful, I won't need that comparison in
the first place.
