"as" keyword woes

One of the things I'd like to point out here is
what we've been learning in new job during
Induction Training...

That is, it's part of the coding standard and
design standards to name variables sensibly.

For instance, naming a variable "db" when it's
really a "database" object is a no no. Instead
you should be naming it "db".

Another example, "db_id" vs. "database_id".

So my point here is that you should not really/ideally
be naming variables with such short un-meaningful
names such as "as", "if", "id", "xs" or what not.

Readability of your code becomes very important
especially if you're working with many developers
over time.

1. Use sensible meaningful names.
2. Don't use abbreviations.

cheers
James
