Although I'm a Christian, I doubt this has any significant impact on my work as a programmer. Religion (or I should rather say 'faith' as I despise the word itself) doesn't affect how I write my Perl code, althought, it does come into play in my dealings with other individuals. My faith has taught me to be tolerant and respectful of other people's beliefs and opinions.
I don't think my/your/someone else's coding would take on a different form simply due to the fact you are a christian, a muslim, or an atheist. For example, I don't draw on verses in the Bible to come up with my variable names. There are no religious undertones in any of my programming work. I feel that had I done otherwise, it would discomfort other developers on my team who might have their own different 'gods' (faiths).
