Gerald Wodni implemented the VOC-DOT notation for VFX as a
recogniser. To reference a word in another vocabulary, just use
   <voc>.<word>
This notation has proven to be very useful, especially when dealing
with a range of byte-oriented serial devices, e.g:
   i2c.emit
   spi.emit

  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.
 

Another piece of history.
In Tcl, the sequence "::" for accessing namespaces was introduced in 1997[1].
In Erlang, the sequence ":" (sic one colon) for accessing namespaces (which are essentially modules) was since its initial release in 1995.
