S02 says "A bare closure also interpolates in double-quotish context."
I presume that there are no restrictions on the code inside that
closure, but all the examples I've seen have nothing but expressions
inside the closure (though some examples, admittedly, do invoke subs
and/or methods).
Question 1: Does
my $s = ''
say "Fire in the hole!{
for reverse 1 .. 3 { $s = qq[$s $_]; }
$s
} BOOM!";
work? I.e., does it say this?
Fire in the hole! 3 2 1 BOOM!
I'm not arguing that embedding that much code in a string is good style.
I'm just asking if it's forbidden.
Question 2: Does C<for> return the value of its last statement? In other
words, does this have the same effect as the previous example?
my $s = '';
say "Fire in the hole!{for reverse 1..3 { $s = qq[$s $_] }} BOOM!";
Question 3: Do quotes inside a closure inside a string get parsed
exactly as if they were in code, or do they screw up the scanning of the
outermost string? If the closure contains "real" code, then I should be
able to replace qq[$s $_] with "$s $_" in the example. Does this work?
my $s = '';
say "Fire in the hole!{for reverse 1..3 { $s = "$s $_" }} BOOM!";
# does this quote end the scan of string? -----^
