If the something has to be done at the beginning, we have a tool 
for that: static this (on module level). The 
mixin(registerMethods); at the top should therefore mix in.

   static this() { updateMethods(); }

It's never wrong: Calling it in main, too, will at most be 
redundant. You can still call it manually, but for the part of 
main, you cannot inadvertently forget it. You can still have 
static this in that module as you may have multiple static this.
