The indentation code has a list of rules, and it runs each rule top-to-bottom 
until one rules matches, then it uses that rule to determine how much to 
indent. The ordering of each rule could be tweaked so that most frequent case 
comes forward. We can also arrange these rules not linearly but in a tree, so 
if one rules matches/doesn’t match, some other rules can be skipped.

What exactly did you compile? I tried byte-compiling indentation rules before 
but didn’t see a significant speed-up.
