docs: assert_raise example is a compiler warning in Elixir 1.18 #14111
Description
Elixir and Erlang/OTP versions
Erlang/OTP 27 [erts-15.2] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit] [dtrace]
Elixir 1.18.0 (compiled with Erlang/OTP 27)
Operating system
macOS 15.2
Current behavior
The documentation for assert_raise suggests using 1 + "test" to get an Arithmetic Error.
https://hexdocs.pm/ex_unit/ExUnit.Assertions.html#assert_raise/2
assert_raise ArithmeticError, fn ->
1 + "test"
end
Expected behavior
While an Arithmetic Error is still the case at runtime, Elixir 1.18 provides a compiler warning for code like this, so maybe it's no longer the best example?
The RuntimeError provided is a better example. Should the ArithmeticError example be removed?
