syntax_error/1

Description

syntax_error(Description)

Throws a syntax error. This built-in predicate is declared as a private method and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of calls:

...,
context(Context),
throw(error(syntax_error(Description), Context)).

This allows the user to generate errors in the same format used by the runtime.
