Functions as arguments

[timjb]

I wanted to use functions as arguments in the examples. When I entered the examples below, the following message appeared:

Evaluation failed.
This should not normally happen. Cannot evaluate function application. Left-hand side is not a function! Please report an issue.

Implicit parameters:

let f x = ?g x
in f 3

Dataflow computations:

let f x g = g (prev x) + (prev g) x
in f 3

Thanks for reporting this - the issue is that the user interface can currently let the user enter only numbers in the textboxes. In both of the samples above, the user would need to enter a function value (as a value for the implicit parameter ?g or as the value for the stream).

This would be a nice feature to add - I suppose the GUI could detect what type you need and parse the input (rather than just treating it as a number currently).
