Thanks for your reply, but no, let me clarify:

I do not want 123\`456\`789 or whatever else custom delimiter.

I just want to output what is already set in the LC_ALL locale 
environment variable which in my case results in 123,456,789 
which of course I can mimic hard-coding it, but the idea is ... 
quite the opposite.

The ` (backtick) I used in my example was from another example I 
found somewhere on the net saying that, when you use the backtick 
character after issuing a setlocale() call, you'll get the output 
accordingly to the LC_ALL variable. Needless to say I am not sure 
whether this is correct or not because the documentation I came 
across is confusing to say the least; furthermore, someone saying 
not every implementation is compatible with this behavior and 
someone else claiming it works for POSIX or the reverse I do not 
remember correctly right now.

I do not need to use std.format.format().

I can welcome any other function in the standard library to 
achieve this.
