Abbreviate varinfo signature and re-order for consistency

The signature line is very long, so I dropped the ::Bool annotations which imo don't add value. I also switched from mixed `m=Main` and `imported = false` style to consistent `m=Main` and `imported=false`. Consistent within a single line is  better than inconsistent, and I chose more concise because we're well over the line limit.

Also reorder the function arguments to match the docstring. NFC, but might avoid some confusion for IDEs that show the actual signature.
