Sorry for the delay. I'm finally reviewing!
This is a sort of random collection of reactions. Sorry for any confusion to
my thoughts.
special variable C<$!> -- should link to perlvar, since $! is a bit weird
You write:
"The other important thing to notice is that, just as in the shell, any
whitespace before or after the filename is ignored."
But:
~$ perl -E "open( my \$fh, '>', 'foo '); print {\$fh} 'hi'; close \$fh; say
-e 'foo ' ? 1 : 0; say -e 'foo' ? 1 : 0"
1
0
...which indicates that you are wrong. I believe this is only true of two-arg
open. I am concerned by this inaccuracy, as it may foretell more to come on
subtler points.
For example, again:
~$ head -1 dupes
use 5.16.0;
~$ perl -E 'my $x = "dupes\n"; open my $fh, "<", $x or die "cannot open $x:
$!"'
cannot open dupes
: No such file or directory at -e line 1.
Or:
~$ cat files.txt
dupes
~$ perl -E 'while (<>) { open my $fh, "<", $_ or die "cannot open $_: $!";
print <$fh>; }' files.txt
cannot open dupes
: No such file or directory at -e line 1, <> line 1.
I think at this point I'm going to stop. The whole document needs to be
checked for accuracy of these kind of claims before it is possible to even
consider merging.
Committers: do not merge this branch yet.
