A Peek into F# 4.1
I'm not a fan of the new syntax for struct tuples, struct records, and struct unions. I feel like it could have been avoided with a lesser evil if they had followed the same approach that Scala is using for anonymous functions in the upgrade to 2.12.<p>Specifically, <i>don't introduce new syntax</i>, but force your users to deal with the fact that your bytecode is now incompatible with previous versions and now requires a new minimum version for the VM. They can recompile...it's not really that big of a deal. It is far more of a big deal to rewrite all of your code than it is to upgrade your VM and recompile.
