Bug #16050
closed:@ is not parsed correctly
Description
Symbol literal allows @
as the first character:
:@foo # => :@foo
Nevertheless, it does not allow @
by itself:
:@ # >> SyntaxError: `@' without identifiers is not allowed as an instance variable name
This resembles #10463, but while #10463 is related to placeholder in a method name, the issue here is related to instance variable name, so I think they are different issues.

I don't think this is a bug. Just because :@iv
is valid syntax does not imply that :@
should also be valid syntax. You should use a quoted symbol (note that Symbol#inspect
quotes the symbol):
:'@'
# => :"@"
'@'.to_sym
# => :"@"

Ah, but :@1
is not parsed either, even though it's now (unfortunately) valid as a numbered block parameter.
Depending on how #15723 goes, :@1
and/or :@
should be parsed if they are valid identifiers.
