Oh. Even having read about hot code swapping and on the fly compilation, as
a newbie I was unable to connect them with a simple thing like streamlining
configuration.
Yes, now I can see I can compile a module on the fly and the problem with
function pattern matching goes away as what before was a variable (loaded
using application:get_env) now becomes a literal value. Thanks a lot.
