   OK, how would you do it?

I would make sure A and B are always strings and use ‘concat’.
For filenames, i would use ‘(expand-file-name B A)’.

   But you understand it, right? I mean, what I mean?

If i answer "no", then both of us may be fooling ourselves,
but in a safe way.  If i answer "yes", then there is only
one fool (me), but the foolishness i am capable of is huge.

   The result of the _insertion_ of literal values at the
   places of the parameters, will result in a function
   that don't use variables (dynamic or lexical) but
   _hard-coded_ values - that issue is _eliminated_.

   Do you think it is correct in terms of technology?

Mu!  (See above.)  Actually, i'd add "places" and "will
result" to my list of confusions.
