scalarref interpolation using postfix deref inside a string is misparsed

[karenetheridge]

to reproduce (I tried this on both 5.26.3 and 5.33.2 with the same results):

$ perl -wle'my @list = ( \"hello" );  print $list[0]->$*'
hello

$ perl -wle'my @list = ( \"hello" );  print "$list[0]->$*"'
$* is no longer supported as of Perl 5.30 at -e line 1.

I think this is related to the change made by dcb414a

I think you want to use something like this inside a string

> ./perl -wle'my @list = ( \"hello" );  print "${list[0]->$*}"'
hello

To make interpolation work, you need to enable the postderef_qq feature (or just use -E):

> perl -E'my @list = ( \"hello" );  print "$list[0]->$*"'
hello

Thanks @xenu for that additional input, I think we can close this case, @karenetheridge can you confirm?
thanks

[karenetheridge]

this works:

perl -wle'use feature "postderef_qq"; my @list = ( \"hello" );  print "$list[0]->$*"'
hello

But there is still a bug, because postderef_qq is documented as being enabled all the time (just as postderef is) from 5.24 onwards. The 'use feature' line should not change anything.

Only 'postderef' is enabled by default. The documentation is possibly not specific enough about this.
