The attached file contains the following code: > multi fib(0) { 0 } > multi fib(1) { 1 } > multi fib(Int $n where * >= 0 ) is cached { fib($n - 2) + fib($n - 1) } > > say fib(18); ...which, when run, results in the following error message: > Cannot invoke object with invocation handler in this context > in block <unit> at test.p6:5 The proper way to fix this code is declare proto fib(Int $) is cached { * }, but that's not obvious from the error message. I'm not sure if this happens with other Routine traits, but I wouldn't be surprised.
