in thread Bug in substitution operator?

I get the same error in both examples:
use strict; my $v = 'x'; print qq"$v{a}"; __END__ Global symbol "%v" requires explicit package name at rhesa1.pl line 3. Execution of rhesa1.pl aborted due to compilation errors.
I agree that the attention should be moved to double quotes, anyway. This gives the very same error as above:
use strict; my $v = 'x'; print qq{$v\{a\}}; __END__ Global symbol "%v" requires explicit package name at rhesa3.pl line 3. Execution of rhesa3.pl aborted due to compilation errors.
while this doesn't:
use strict; my $v = 'x'; print "$v\{a\}"; __END__ x{a}
I'm not convinced that it'is an incarnation of the problem described in the documentation, anyway: in our case we have a different behaviour in the very same string when the double-quoted string is delimited with different characters, which is not what's discussed in the docs.

Io ho capito... ma tu che hai detto?

[Corion]: choroba: Ooooh - I didn't think of that! I write my presentations as POD and if it "roughly" looks like Perl code, I should also syntax-check that...
[haukex]: Yes sorry I don't run them all the time, my POD tests are only run as author tests (and are excluded when I'm using Devel::Cover)
[Corion]: choroba: Hmm - no, I keep the snippets inline, but as my framework also has support for capturing output etc., maybe I should do the same...
[Corion]: haukex: Yes, that approach is sane, and it heals the fragility of Pod parsers in a nice way while still syntax-checking stuff
[choroba]: Unfortunately, none of it is online
[haukex]: I figured that POD tests make sense, but only as author tests
[choroba]: I mean, the slides are, but not the makefile with scripts to create them
[Corion]: haukex: I've only now arrived at that revelation ;)
[Corion]: choroba: I use spod5, which also has that support, and also implements its own kinda-make stuff
[haukex]: But that module I just linked to assumes that most verbatim blocks are runnable code, I have other modules where that's not the case, so there I just copy-and-paste the synopsis into the author tests...
