welcome! [Re: Scope/block behaviour]

[Graham Fawcett]

Hi Eduardo,

I just wanted to welcome you to the list! I've come across your posts
(on Scheme and Factor) on various other lists, and I've enjoyed the
self-contained experiments you've posted about those languages. (You
may have a compatriot in our resident member Bearophile, whose posts
sometimes remind me of yours.)

I hope you'll stay for a while, and share your enthusiasm and design
sensibilities with the D community.

Cheers,
Graham
