This module defines Erlang BIFs, guard tests and operators. This module is only of interest to programmers who manipulate Erlang code.

 Test for an Erlang BIF

Returns true if Name/Arity is an Erlang BIF which is automatically recognized by the compiler, otherwise false.

 Test for an Erlang BIF allowed in guards

Returns true if Name/Arity is an Erlang BIF which is allowed in guards, otherwise false.

 Test for a valid type test

Returns true if Name/Arity is a valid Erlang type test, otherwise false.

 Test for an arithmetic operator

Returns true if OpName/Arity is an arithmetic operator, otherwise false.

 Test for a Boolean operator

Returns true if OpName/Arity is a Boolean operator, otherwise false.

 Test for a comparison operator

Returns true if OpName/Arity is a comparison operator, otherwise false.

 Test for a list operator

Returns true if OpName/Arity is a list operator, otherwise false.

 Test for a send operator

Returns true if OpName/Arity is a send operator, otherwise false.

 Return operator type

Returns the Type of operator that OpName/Arity belongs to, or generates a function_clause error if it is not an operator at all.
