[erlang-questions] case expression scope

[Anthony Ramine]

The compile option is warn_export_vars:

	Causes warnings to be emitted for all implicitly exported variables referred to after the primitives where they were first defined. No warnings for exported variables unless they are referred to in some pattern, which is the default, can be selected by the option nowarn_export_vars.
