Gravity is a nice language with nice additions like not, and, or and the ".." / "..." range operators. Also the optional semicolon is a great improvement.
There's only one "but" ;).
I hate the braces used for code blocks as used in C-like languages. For me that makes the code cluttered, especially when the code block doesn't fit on the screen. In that case you often see several close braces of which you don't know to which block they belong to.
Because of that I would like to suggest an alternative block notation, as used in Basic like languages.
for (var i in 1..10) .... endfor I set ... endset get ... endget class x ... endclass x
Or, if you believe this isn't suitable for Gravity, show some info (eg. in status bar) that shows in which code block the cursor is currently in.
For example, if I'm in a for-loop code block, the info could show:
for (var i in 1..10) ...
So only the block definition, what would be enough to know.
