I don't know if this is expected, but this (bad) program causes the go2go playground to give "panic: assertion failed"
https://go2goplay.golang.org/p/VH5SLJNxw3X - I think it's the compiler itself that's panicing, not the runtime (since it doesn't get as far as the next line). ---- Aside: my general feeling so far is that the error messages given from go programs which misapply generic syntax can be very unhelpful. Here's one example: https://go2goplay.golang.org/p/m9YUDBTWwpA Error given: "missing ',' in type argument list" Actual problem: a constraint was used in a place where it's not allowed -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
