Consider these cases:
[=] $x, $y, $z;
[+=] $a, $b, $c;
S03 is currently inconsistent. It first says these are not supported:
The final metaoperator in Perl 6 is the reduction operator. Any
infix operator (except for non-associating operators and assignment
operators) can be surrounded
The formal definition of "Inf" appears to be missing from the spec
documents. Since I'm not exactly sure how Perl 6 treats "Inf", I'll
leave submitting this patch to someone else.
Once the spec is added, a smart link to it should be added from:
t/builtins/math/infinity.t
