There will usually be a `foo-mode-hook' for any mode `foo', so you would
create a function to perform you configuration and add it to that hook.
There's also an `after-change-major-mode-hook', where you can add
functions that you want to be run after the major mode changes. However,
in practice I've never needed to use it.
As an aside, the value of `major-mode' is a symbol, so `=' won't work
for the equality comparison (unlike in Clojure, `=' isn't very
polymorphic; it can only compare numbers or markers). Either `eq'
(equivalent to Clojure's `identical?') or `equal' (the closest to
Clojure's `=', though not equivalent) would work.
