Dear all! Please, may I ask you a few questions regarding concatenative languages in general? This is not strictly about Factor so I apologise if it is not appropriate here.
1. Concatenative languages vs. tacit languages What is the difference? Is there any at all? 2. Composition I think I read somewhere that "function composition" is just "concatenation" of two programs. Does it mean that I can cut any portion of some program a paste it anywhere into some other program and it will just work? Doesn't it make some assumption about the stack's content, for example, which would make the program break? 3. Instruction set What is the minimal set of operations for a concatenative languages to be Turing complete? I mean, how does the the most minimal concatenative language look like? 4. Quotations Is it fundamental to be able to pass around unevaluated code? I mean, what is the reasoning behind "quotations"? Are they necessary for a language to be Turing complete? 5. Types I read that it is also possible to have "types" concatenative language. In broad terms, how does it work? Does the evaluation simply skips the types it doesn't recognise? Does it throw an exception if attempting to add a number and a string?
