.gist
hangs indefinitely on a lazy array passed to a slurpy paramater
#5331
Comments
From @smlsThe .gist call in the following code hangs indefinitely: my @a = 1..Inf; foo @a; sub foo(*@_) { say @_.gist }; It shouldn't hang, because checking the argument for laziness returns True, and indexing it does not hang either: my @a = 1..Inf; foo @a; sub foo(*@_) { say @_.is-lazy }; # True And now, this is where it gets really weird: When calling `.is-lazy` or `.[]` on the parameter *first*, then a *subsequent* .gist on it no longer hangs: my @a = 1..Inf; foo @a; sub foo(*@_) { say @_.is-lazy; say @_.gist }; # True[...] For comparison, here are some variations which also do not hang: my @a = 1..Inf; say @a.gist; # [...] my @a = 1..Inf; foo @a; sub foo(@_) { say @_.gist }; # [...] my @a = 1..Inf; foo @a; sub foo(*@_ is raw) { say @_.gist }; # (1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 ...)
