I think it's just as-yet-unimplemented.
That said, if you have a seq{} expression, you can usually 'simulate' a break with a 'bool ref' named e.g. 'finished' and an extra conditional expression.
EDIT: In writing this post I cleared up a bit of muddled thinking on my part.
Brian - good to know yield break is on the cards for a future release.

Danny
My understanding is the for FP, you transform data in the form of f(x) = y so breaking a loop doesn't conceptually fit.
The standard way is either your filter out things via filter(seq) or you use takeWhile
Why would you need a break ? I used to code using break/continue but now find the code easier to reason(and maintain) without them.

Hi,
I enjoy using both seq {} expressions and the Seq combinators to construct sequences. However I find that if I need to add an explicit stopping condition to a seq {} expression I'm forced to rewrite it using the Seq combinators rather than simply include a yield break.
Is yield break a deprecated construct in functional programming or are there simply technical reasons that it hasn't yet been implemented in F#? Any insights here would be much appreciated.
regards,
Danny
