[Pdx-pm] Fwd: Re: subroutine calls CAN be string-interpolated!

In case anyone missed the connection, I've forwarded the chunk from the 
previous discussion of a closely related topic.  The qr// is a 
string-interpolating quote operator.

According to:

 http://www.nntp.perl.org/group/perl.fwp/3727

the @{[]} "secret operator" was invented by Randal and/or
Larry in 1994.

BTW, cog dreamed up a (presumably) vulgar name for the @{[]}
operator, as alluded to here:

 http://www.nntp.perl.org/group/perl.fwp/3726

I don't know what this name is though.
