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

 Add code for pre-defined functions.

Adds to Forms the code for the standard pre-defined functions (such as module_info/0) that are to be included in every module.

 Test for an arithmetic operator.

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

 Test for an Erlang BIF.

Returns true if Name/Arity is an Erlang BIF that is automatically recognized by the compiler, 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 an Erlang BIF allowed in guards.

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

 Test for a list operator.

Returns true if OpName/Arity is a list 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.

 Test for a send operator.

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

 Test for a valid type test.

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