The answer depends on our views about approaches how customised
make functions should be safely written.

I sent it just as another follow-up in the hope to reduce a few
of our communication difficulties.
Can such tiny code examples help in this dialogue at all?

I hope that there will no confusion occur with subjects from
my other recent discussion threads.
I am still curious about information I presented at 10:28.

Repetition:
1. Will it make sense to extend any documentation for ‚Äúsubstitution references‚ÄĚ?

2. Can the distinction between appending suffixes and replacing them become
   occasionally more relevant for better software build characteristics?


Another software extension:
How are the chances to assign aliases to numbered temporary variables?
