Re^2: uparse - Parse Unicode strings

With my original code, the messages look like this:

$ uparse
/home/ken/local/bin/uparse requires Perl v5.7.3 or later.

$ uparse
Usage: /home/ken/local/bin/uparse string [string ...]
[download]

With your suggestion, the messages look like this:

$ uparse
/home/ken/local/bin/uparse requires Perl v5.7.3 or later.
BEGIN failed--compilation aborted at /home/ken/local/bin/uparse line 1
+5.

$ uparse
Usage: /home/ken/local/bin/uparse string [string ...]
BEGIN failed--compilation aborted at /home/ken/local/bin/uparse line 1
+5.
[download]

I didn't want the "BEGIN failed--compilation aborted at ..." lines.

Thanks - I understand now. It's for neatness of output (well, stderr really) and is only an issue because of the BEGIN block which itself is necessary for the version check to fire before we hit newer syntax/features. 🦛	[reply]
