@adeveloper Can you provide some examples of why that's needed and how that would work using a preference based system please? I'm not sure I understand the need or solution well enough to agree or disagree.

Without getting into a bike shed type argument about it, having strict datatypes as Vuo does makes it more functional than object oriented I think. I'm not sure if it has lazy evaluational the way QC does for example, another characteristic of a functional language. One of the problems though is the types aren't expansive enough as they stand (no lists of lists for e.g.) and users can only extend types by writing C code.

Any functional language thrives or dies on compositional expressiveness and the ability to create higher level functions from lower level functions. To me sub compositions are not really doing that yet in Vuo, it's too hard to manufacture higher level functions from lower level ones. With QC type Macros as an intermediary step for development I feel like it will engender more of that kind of coding. I agree having too many nodes on the canvas is a deterrent to major work in Vuo.

I'm not smart enough or skilled enough to know if Lambda's in Vuo could be implemented successfully or not. I'm just teaching myself Haskell after a 3 day training course for professional coders run by Lab61 in Australia — I was quickly out of my depth but am totally hooked on the concept of pure functional programming as the coding method of the future.

Sub-composition published port names get blocked for reuse.

How severely does this bug affect you?: 

●●○○ — It's annoying but I can work around it.

Steps causing the bug to occur: 

  1. Create a sub-composition with some published ports
  2. Erase one of the published ports (input or output)
  3. Create a new published port with the same name and place as the erased port (input if erased one was input, output if erased port was output)
  4. Result is the digit "2" appended to the port title.
  5. Rename port to erase the "2" and it becomes a "3"

Have you found a workaround?: 

No.

Other notes: 

It means that when reworking a sub composition you can break wires coming out of it in the parent compositions because it forces a port title change on you which, which obviously breaks the link to other nodes in the parent compositions. Forced to rewire them, and an annoying port name too.

Editable Value fields on Editor canvas to increase in scale when view is zoomed in beyond actual size.

Sometimes I zoom in to read the small expressions in Calculate nodes, especially at night time. While the expression in the canvas is enlarged as you zoom in (but truncated), if you double click the field to edit it, the text is still the small size as per an "actual size" zoom magnification. SO it's still hard to read on a big screen for me at night a fair distance from my eyes.

As illustrated below.
