Unless you 'wanted' to interpolate

my $bar = "$  foo and $cake";

Or a more likely example

my $bar = "$ $total_foo_dollars";

I had no idea that spaces in quotes could be abused this way and it just feels so wrong.

How about

my $foo = ['a', 'b', 'c'];
my $bar = "$   foo -> [2]";

[download]

vs

my $foo = ['a', 'b', 'c'];
my $bar = "$foo->[2]";

[download]

Before reading this thread I would have a clear answer for what the result of $bar would be in each case. After reading this thread I had a less clear different answer. And after actually testing the code I can see now that I was wrong in all my assumptions. Now I've got a nagging feeling that I should review all my code for unintended quoting results.
