It's OK for the time being to declare variables inside $() in qq
strings like this. But Rakudo complains about redeclaration, and it
shouldn't. Note that STD.pm6 doesn't.

@coke - Status changed from 'new' to 'open'

Same behavior in rakudo 38907e.

Seems to work fine now​:

say "foo$(my $x = 42)bar"; say $x
foo42bar
42

Tagging testneeded.

From @usev6

stmuk added a test for this recently​: Raku/roast@b4fc0fe

I moved the test from S02-names-var/76608.t to S02-literals/misc-interpolation.t (which is in 't/spectest.data').

The test passes on all rakudo backends.

@usev6 - Status changed from 'open' to 'resolved'
