Yes -- it is in Modula-2.

Further to this thread, look at the source for the compiler.  The
initialisation part of the parser enters "SYSTEM", "VAL", "VAR", and
all the other special procedures into the symbol table, each with its
own "type" and pre-determined rules.  When the parser finds one of
these special types, instructions are generated according to
pre-determined rules.
