<FROGGS> p: say (1,2).Str
<camelia> rakudo-parrot 46234b: OUTPUT«1 2»
A Parcel stringifies to "1 2". Then you used the string repeatition
operator "x", and I think you want to use the list repeatition operator
"xx" instead.
<FROGGS> p: say join("|", (1,2) xx 10)
<camelia> rakudo-parrot 46234b:
OUTPUT«1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2»
Then again, you might want to do this instead:
<FROGGS> p: say join("|", (1,2).Str xx 10)
<camelia> rakudo-parrot 46234b: OUTPUT«1 2|1 2|1 2|1 2|1 2|1 2|1 2|1 2|1
2|1 2»
