You can even steal a trick I've used several times

Heh, believe me I thought of it already. And yes I thought of it as "tye's trick", from one of the registry tools you posted. :-) The problem with it was that I couldn't (and still can't) see how I can use a single wrapper with multiple scripts this way. I was worried about multiple scripts modifying the batch file simultaneously. And if I wrap all the scripts in the first place then I might as well just modify pl2bat to do the right thing in the first place.

But using start with a specific name hadnt occured to me. Good idea. Thanks.

I couldn't (and still can't) see how I can use a single wrapper with multiple scripts this way.

Something like this, maybe?

@echo off
REM
REM   nperl.bat
REM
REM Assumes %1 holds perl script

copy /Y C:\Perl\bin\perl.exe %1.exe > NUL

%1.exe %*

del /Y %1.exe > NUL
[download]

Put it in your path, and call it as: nperl script.pl args

I tried to figure out a way to avoid hard-coding the path to the perl executable, but Windows batch files are pretty limited and I couldn't come up with one.

Update: This might not work on earlier versions of Windows (ie, pre-2k? non-NT based?), as they don't support the %* construct. (At least, I don't think they do.)
