No, I've just skimmed over some of its chapters to clarify some concepts. I've mostly learned by reading code and then trying to implement my own type systems. Algorithm W is really quite simple and basic.

Another good resource could be Programming Language Zoo http://plzoo.andrej.com/ that covers different evaluation techniques as well.

In general, I've been "involved" in PL design for quite some time, so I've no idea where I've gained all the knowledge I have... but in recent years, there have been quite a few modern resources, even a few on HN IIRC!

e.g.
