Re: [Nmh-workers] [exmh-workers] Second release candidate for nmh 1.5 is now available

$_ is a special global, you lexicalize these with local not my,
especially if you want to be backwards compatible ;-)

Although 5.8 is a bit old, it's still common and has good Unicode
support, therefore as long as the changes to support are minimal
I suggest it is well worth doing.
