I have used Forth, PostScript, dc, and other stack-based prorgamming. However, mostly in PostScript code I have not seen the Forth-like notation for the stack effect, although I do use that in my own PostScript programming, because I think it is better than the notation Adobe uses.

Some virtual machine instruction sets (such as Glulx and Z-machine code) still require instruction operands but allow some or all of them to be optionally specified as stack operands. This allows you to have both stack and a register-like programming.
