This PR fixes the crash reported in python#8230, by replacing the 'pass' with the 'continue', as suggested. However, it does *not* fix the underlying root cause -- I don't think I actually understand the relevant pieces of code enough to feel confident volunteering a fix. So, I settled for just fixing the regression. Basically, it seems this bug is due to how we try inferring the type of the lambda in multiple passes to resolve the types. We pencil in an ErasedType during the first pass -- and then subsequently crash when attempting to type check the body during that pass. I'll leave more details about this in the linked issue.
