True, the *LIBL concept is used widely on the AS/400, but in this case, it
can be more of a headache (my view) than a help. If I have a *MODULE and a
*SRVPGM that both export PROC_A [but the *MODULE one takes a pointer as the
parm, the *SRVPGM one takes a PKD as the parm] in my *LIBL which one should
CRTPGM 'choose' to use for me ? Hitting this problem actually displays the
poor design of the whole BNDDIR concept - that you can't have nested
BNDDIR's, instead we either accept that we'll get binding errors (that can
be overridden, in my view dangerously, with OPTION(*DUPPROC)) or we create
lots of custom BNDDIRs and use them on the BNDDIR parm to CRTPGM to filter
out the duplicates before they get to CRTPGM.

As for the explicit lib/module parameter of the CRTPGM cmd, sadly, CRTPGM
binds all the modules listed in the list, even if they are never referenced,
leading to bloated objects containing orphaned *MODULEs.
