Good catch!

> It has nothing specifically to do with POSTMATCH,

I think the crucial point is that a $variable is passed by reference (read alias)

Compare

  DB<25> sub tt { print "@_"}

  DB<26> tt ( ($foo = 1) , ($foo = 2) , ($foo = 3) )
3 3 3
  DB<27>

So the implementation of concat was changed in a function way...
