Such a syntax is used in SP-Forth/4 since 2001, in the form <voc>::<word> or <voc1>::<voc2>::<word> Where <voc> is a word that returns wid, or a word that is created with `vocabulary`. This syntax in SP-Forth probably came after C++ "::" operator, introduced in 1998. The same operator was in C# from its initial release in 2000. The dot "." operator for accessing nested packages in Java was introduced in 1995. In Forth, a dot is often used as part of plain names, so it was less suitable as a namespace separator. -- Ruvim
