- <p>By default, the compiler will issue an error or warning
- when replacing an auto-imported BIF. For local functions
- having names clashing with an auto-imported BIF, the error
- or warning is issued whenever it is called without using a
- module prefix. For explicitly imported functions, the
- error or warning will be issued as soon as it's imported
- (regardless of calls). If the auto-imported BIF was present
- before OTP R14A it will be a fatal error to override it,
- otherwise only a warning will be issued.</p>
+ <p>This option is removed, it will generate a fatal error if used.</p>
<warning>
<p>Beginning with R14A, the compiler no longer calls the
auto-imported BIF if the name clashes with a local or
explicitly imported function and a call without explicit
module name is issued. Instead the local or imported
- function is called. Use of <c>nowarn_bif_clash</c> makes a
+ function is called. Still accepting <c>nowarn_bif_clash</c> would makes a
module calling functions clashing with autoimported BIFs
compile with both the old and new compilers, but with
- completely different semantics, why a warning is always
- issued if any code uses this option.</p>
+ completely different semantics, why the option was removed.</p>

- From OTP R14A and forward it's also deprecated.</p>
- <p>The only module who actually could have some legitimate use for
- this option is the module <c>erlang</c>, which in
- itself contains auto-imported functions, other modules
- should never use it.</p>
