Maybe it's a crazy idea, but what if we could decorate a single line of code?

For example:

@Timer a = time_consuming_function()

Syntax-wise, I don't see any problems. As I mentioned in a recent mail, "@" here is effectively a prefix operator (unary in first approximation).

But is that really compelling usecase? What if you want to time 2 statements?

Thinking about it more, that would require introducing some kind of "brackets" to delimit "decorated" statements, e.g.: @Timer{ foo bar @} And then it's just one step more to switch to brace-based alternative syntax altogether.
