While you are correct in your statements about interpolation, your second system call will not store anything in $foo[0] besides 0 (or, possibly, 256). The difference between system and qx is quite important - the former returns the return value of the code's execution, and the latter will return the output from the code's execution.

Should you desire to keep the string passed to a qx from interpolating, use single quotes as the delimiter, like so:

@foo = qx'echo $HOME';

Which should store "/home/cheesy\n" or something like that in $foo[0]. I hope that helps...

Update: Changed emphasis in a few places.

Update #2: The node I replied to has had its content altered in a way that makes this node make no sense... the original second system call was as follows:

@foo = system('echo $username[0]');

I hope that clears up any confusion.
