   I'd say factor is a Forth with lispy features, like garbage collecting.

   A strong type system is not a problem for embedded applications, as long   
   as there is a means to defeat the type system.   
   Ada was designed with this in mind, making distinction between safe and   
   unsafe modules. Remember that c++ was an afterthought after c that was   
   not well designed in the first place.   
      
   Strong typing can be annoying. I remember wasting time passing a filename   
   to function that expected a     `const char *` or something, and it is   
   by no means obvious what you have to do, so you are lured into casting.   
   A lot of people do not understand that casting is a means to defeat the   
   type system, so that you loose the advantages.
