Perhaps you'd like
use constant PIE_NO_BACKUP => '';
sub pie(&$@) {
(
my $code, # Code ref
local $^I, # PIE_NO_BACKUP, '~', '.bak', etc
local @ARGV,
) = @_;
local *_; # Protect caller's $_.
while (<>) {
chomp;
$code->();
print($_, "\n");
}
}
# perl -i -pe 's///' file1 file2
pie { s/// } PIE_NO_BACKUP, 'file1', 'file2';
# perl -i.bak -pe 's///' file? data*.txt
pie { s/// } '.bak', map { bsd_glob($_) } 'file?', 'data*.txt';
Untested.
Update: Added missing "\n". Created constant for no backup. Added local *_;.
