Variable capture and TypeScript / C#

[Benjamin Gruenbaum]

One advantage other languages have over our blöck syntax so far is that they make it very easy to capture variables in the closure passed to the thread/task-factories.

Block syntax can be really useful when coupled with an AST facility in order to implement really cool stuff (like C#'s LINQ).

IIRC there was an interesting discussion about the possibility of implementing this with capture for TypeScript that was shut down for performance reasons. I think it would be really cool if the people involved would weigh in - I think I recall @ahejlsberg

I tried to look for something summarized but couldn't find any.
