With this commit, the examples for exp_m1 would fail if x.exp() - 1.0 is used instead of x.exp_m1().
With this commit, the examples for ln_1p would fail if (x + 1.0).ln() is used instead of x.ln_1p().
When calling a function that doesn't exist inside of a trait's associated `fn`, and another associated `fn` in that trait has that name, suggest calling it with the appropriate fully-qualified path. Expand the label to be more descriptive. Prompted by the following user experience: https://users.rust-lang.org/t/cannot-find-function/50663

Directly casting the opaque pointer was [reported] to cause an
"incomplete type" error with GCC 9.3:

A simple `unwrap` fixes the issue.
Add std::panic::panic_any. The discussion of #67984 lead to the conclusion that there should be a macro or function separate from `std::panic!()` for throwing arbitrary payloads, to make it possible to deprecate or disallow (in edition 2021) `std::panic!(arbitrary_payload)`. Alternative names: - `panic_with!(..)` - ~~`start_unwind(..)`~~ (panicking doesn't always unwind) - `throw!(..)` - `panic_throwing!(..)` - `panic_with_value(..)` - `panic_value(..)` - `panic_with(..)` - `panic_box(..)` - `panic(..)` The equivalent (private, unstable) function in `libstd` is called `std::panicking::begin_panic`. I suggest `panic_any`, because it allows for any (`Any + Send`) type. _Tracking issue: #78500_
make exp_m1 and ln_1p examples more representative of use With this PR, the examples for `exp_m1` would fail if `x.exp() - 1.0` is used instead of `x.exp_m1()`, and the examples for `ln_1p` would fail if `(x + 1.0).ln()` is used instead of `x.ln_1p()`.

Add a test for compiletest rustc-env & unset-rustc-env directives ... and move compiletest meta tests into a separate directory.
