My first thought was indeed just to add an extra space, but it occurred to me
that it's not easily remembered. Consider the original documentation:

I can split it into another patch.

How about:
while (local $_ = <$fh>)
Or, in our case, this:
while (my $_ = <$fh>)
In testing these, I came across behavior that I think is incorrect, and I
have a mind to complain about it to the perl guys:
# Well! the print `function' doesn't seem to play by the rules.
# Example 0
# I expect the output to be:
# 1
# 1
# 3
# and I am right!
$_ = 3;
{
local $_ = 1;
print; print "\n";
print $_; print "\n";
}
print; print "\n";
##############################################
# Example 1
# I expect the output to be:
# 3
# 1
# 3
# But it is:
# 1
# 1
# 3
$_ = 3;
{
my $_ = 1;
print; print "\n";
print $_; print "\n";
}
print; print "\n";
###############################################
# Example 2
# I expect the output to be:
# 1
# 1
# 3
# and I am right!
sub my_print {
print(shift or $_);
}
$_ = 3;
{
local $_ = 1;
my_print; print "\n";
my_print $_; print "\n";
}
my_print; print "\n";
###############################################
# Example 3
# I expect the output to be:
# 3
# 1
# 3
# and I am right this time!
sub my_print {
print(shift or $_);
}
$_ = 3;
{
my $_ = 1;
my_print; print "\n";
my_print $_; print "\n";
}
my_print; print "\n";
