Hello,
Many of you have been asking for this for a long time, and based on feedback (as well as my own experience) the lack of this feature has been the biggest cause of bugs in PS code, so it's with a bit of joy that I just pushed out a patch to add implicit returns to PS functions (including lambdas and flet/labels) to the repository just now. Please try it out and report any bugs you find!
Thank you, Vladimir
