PaddedViews.jl

As sibling posts have pointed out, you can do all of those things: 1. You can trivially write a `getproperty` method for a tuple. It is considered to be type piracy and thus runs the risk of colliding with someone else's definition, but the language absolutely lets you do it. 2. You can broadcast over the fields of a `NamedTuple` by defining appropriate methods. Again, it's type piracy, so take that into consideration, but the language lets you do this easily as well. 3. The https://github.com/JuliaArrays/PaddedViews.jl package implements exactly what you're saying Julia won't let you do. If anything, Julia errs on the side of allowing you to do too many things! There are very few things the language really won't let you do.

For the last thing, is this what you want? https://github.com/JuliaArrays/PaddedViews.jl There may be other packages or methods for doing the other things you want. I’d think that broadcasting over a NamedTuple would iterate over the key => value pairs, but I haven’t tried it.
