Hi Matthew We're going to skip over the reiterations of Juliettes arguments, as they have already been responded to.

I would categorize hooks as declarations, because they are really just functions attached to the property. Declarations are `;`-terminated, or have a body (`{}`) (properties, (non-)abstract methods, class consts, etc). `,`, on the other hand, is used for lists of expressions and other things (array elements, match cases, function arguments). The other argument for the syntax we chose is that it's already used in C#. > (Larry tells me that it's `match()` being weird here, but considering that > for many developers, their only point of reference for this sort of syntax IS > `match()`, making it feel like the language is ignoring its own syntax when > creating new syntax.) Given my description from above, I don't believe this is true either. Match arms most closely relate to the array element syntax, which already uses `,`. > 3.

Our decision to support references (as much as possible) comes from the desire to maintain compatibility (as much as possible), not only with `__get`/`__set` but also plain props. Ilija
