Totally agree - this could actually be a really natural bridge into programming for a lot of people whose advanced Excel skills already have them on the cusp.
Name Manager though... Would be really nice if they could come up with some idioms for writing these functions in a multi-line format, with indentation, and give a slightly nicer editor. I realize that might be a bit tricky without changing the language syntax, but after the 2nd nested if-statement I find that I really struggle to follow someone's single-line Excel logic...
