Creating multiple items in for-in loops

[vladimmi]

As far as I can see, right now we can only have one single item created by for-in loop at each step: for i in 42: Text { text: i; }. Did I miss something probably?

There are cases where you would like to create several items at each step. One possible workaround is to wrap it in a Rectangle. But it's not always possible, for example when you are generating Path contents. Also it adds unneeded extra level to item hierarchy.

Possible syntax can be something like:

for i in 42: [
    Text { text: i; }
    Text { text: i; }
]

Perhaps Slint should add a ghost element, which incurs no overhead whatsoever and exists solely to wrap multiple child elements.
