BCPL had a construct like this, and we did consider doing something analogous, but in the end Go is not an expression language. C and BCPL are, and that property does lead to problems, although they are probably avoidable with careful language design.
But Go is not an expression language, so control flow decisions are done using control flow, and expressions don't appear in many places that they would in other languages. Ifs and switches as expressions, while sometimes nice to have, don't belong in Go. -rob On Thu, Dec 20, 2018 at 8:39 AM Tyler Compton <xavi...@gmail.com> wrote: > There is some precedent.
