AnonymousReporter

Computes and reports a value

When run by the runresult primitive or other primitives which take anonymous reporters as arguments, this is run on the Job Thread. Before invoking this, the NetLogo primitives which use anonymous reporters will check that the number of arguments contained in args is at least as long as the number of arguments specified by the tasks syntax method. It is a user error to run report with fewer args than specified.

Used to specify the number of arguments required to run an anonymous procedure.

Note that an anonymous procedure may be supplied with more arguments depending on the number of arguments supplied to run/runresult. This only used to calculate argument count at the moment. Note that anonymous procedures as created by -> are variadic in the number of arguments they accept. For instance, the anonymous procedure returned by [[x y] -> x + y] can be run with 10 arguments and the last 8 will be ignored. The current versions only makes assertions that the number of arguments is greater than the syntax minimum.

Future versions ''may'' make greater use of the information provided by syntax. Primitives returning anonymous procedures will want to ensure the anonymous procedure's syntax is not more restrictive than the expected argument(s).
