bites shoots and leaves

Composing an email to a work colleague, I wrote, "I just wanted to make sure we're not biting ourselves in the foot".

Something didn't sound quite right about that, so I looked up the expression. Oh, it's usually "shooting", not "biting". That makes more sense. But then I didn't feel like mentioning shooting in the email, and I was copying an Indian colleague who might not be familiar with the expression anyway, so I changed it to a plainer sounding "not causing ourselves potential future problems".

Something else in a recent work email made me smile. The email mentioned "the Metallicize value", and I wondered what that meant, until I looked at the pasted code block and saw a "maxTableSize" variable highlighted.
