CHANGE: **Switching map and construction syntax**
`map!` values now use syntax like: `#[key: value]` construction syntax now looks like: `#(true)` or `#(i32! [1 2 3])` The included [`map-conv.reb` script](https://github.com/Oldes/Rebol3/blob/master/make/tools/map-conv.reb) can be used for converting existing code. resolves: Oldes/Rebol-issues#2589
