Where is the typo? I can't handle your suggestions because your mails constantly
break the threads. I just can't find them after due to missed/wrong In-Reply-To
headers. Again, this mail doesn't contain In-Reply-To header and highly likely I
will miss it when I will prepare next version of the patch.

It's less readable and harder to review.

Ok, I will fix this if there will be next version.

No. It's pointless to break the line to save 5 chars this way.
I can use instead:
coccilib.report.print_report(p2[0], f"WARNING: array_size is already used (line {p1[0].line}) to compute the same size")
or
msg = f"WARNING: array_size is already used (line {p1[0].line}) to compute the same size"
coccilib.report.print_report(p2[0], msg)
or
coccilib.report.print_report(p2[0],
f"WARNING: array_size is already used (line {p1[0].line}) to compute the same size")
And I prefer the last one if Julia will allow me to use more than 80 chars in print string.
Thanks,
Denis
