Is it really idiomatic to use intrinsic truth values (eg, using "if x" instead of "if x != 0")?

Here are my arguments against it:

- "Explicit is better than implicit."

- If there's need for a table as reference for what is intrinsically true and what is intrinsically false, then it's clearly not "elegant" enough for people to just understand from looking at the code.

- Conventions vary across languages. You're basically forcing anyone who looks at your code who's not used tons of Python (and who would otherwise completely understand the code) to look up that table.
