Start port type

[emil14]

First idea was to have Main<T> (start T) (exit int) but then in turns out that using of type-parameters makes no sense there because there's only one use-case always - runtime sends nil (or maybe something else) as a signal to kick execution. Runtime doesn't sends this value further. In other words - it would be easy to use to have simple fixed type for start port.

Configurable start port

Add startMessage parameter and assume there will be start inport that will be triggered by the runtime but instead of sending pointless empty record or nil let it sends the message you want. It will make programming a little bit easier. E.g. - you don't have to use triggers and static ports to implement dreadful "program that does nothing". The same goes for "Hello world"

Empty record

If we won't implement #225 (comment) or #143 then {} seems to be a good choice

[emil14]

Any

#143

[emil14]

Configurable start ports

Same as #225 (comment) but for any amount of ports

[emil14]

Configurable ports via sugar

Implement #225 (comment) but with the sugar stage. Desugar it into "root -> wrapper with constants -> actual logic"

[emil14]

Do not implement

Just do same as de sugaring but manually - use const
