Like C, with its many hidden behaviors?

[uecker]

What hidden behaviors? The only hidden behaviors I can think of which are somewhat problematic in C are implicit value-changing conversions. But one can instruct compilers to diagnose those.

Not hidden, the C standard spells it out. And implementation-defined behavior can be observed.

I would argue that if it needs to be spelled out in a separate document from the code you're reading, then it's hidden.

[tempodox]

You must be joking. Like, you only use languages that don't require you to learn anything.
