Re^3: Aren't there code refs as well as function refs?

yeah, but

quote-like delimiters are a wildmark which fit everywhere
hash-keys - OK you are right - they belong to the already mentioned domain of hashes
in-string metas for unicode are a sub-language like the afore-mentioned regex, there might be even more like sprintf or formats

and I also didn't mention dereferencing @{...} etc., but those belong to the same domain like @{name} and the un-strict symbolic derefs @{"na"."me"}

in short: outside strings (and offsprings like regex) are curlies meant for the domains of

code-blocks
hashes
grouping of variable-symbols/refs

Technically the contents of `${...}`, `@{...}`, `%{...}`, `*{...}`, and `$#{...}` are blocks, so you already covered them. `use v5.10; no strict 'refs'; our $abc = 123; say ${ my @name = qw/a b c/; join q//, @name; };` [download] Hire me at Toby Ink Ltd or Join my OnlyFans	[reply] [d/l] [select]

Hmm, indeed. Actually I was coming from the string-interpolation perspective, and didn't expect the following to "work" `# https://perlmonks.org/?node_id=11150758 use v5.12.0; # incl. strict use warnings; no strict 'refs'; our @abc = 1..3; say "@{'a'.'bc'}";` [download] ---> `1 2 3` Cheers Rolf _{(addicted to the 𐍀𐌴𐍂𐌻 Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]
