The current status of the toy language is still pre-05. I got new motivation to work on the language. So its development will continue... Right now, language-implemented functions cannot have named parameters. And user-implemented functions cannot have unnamed parameters. So in this post, I will discuss my motivation to correct that situation. The hash character will be the symbol used by toy to indicate a many-members variable in the context of function-parameters. Any variable starting with the hash character will be a normal array variable. Arrays will be variable that will save the order of the variables put in (FILO). No variable-target will allowed in an array. So I don't know for now whether a single parameter will be usable for a total call to a function or not.
