Bug reporting etiquette question

Hi All,

I am about to report a regression bug over on

    https://github.com/rakudo/rakudo/issues/new

A question about bug reporting etiquette:

1) to reproduce the bug is 150 line of code.  Do
I attach the code to the bug or do I post it
up on vpaste.net?

2) I have two different revision of Rakudo.  The older one
without the bug and the younger one with the bug.

I am sure they do not want those both attached.  If
the developer can give me his eMail address, I can send
him an Ice Drive invite with my code and the two
Rakudos.  Is this the right way to go about it?

Many thanks,
-T
