Couldn't have said it better myself.
As for the braces in the HEREDOC around {$somevar}, while it works
absolutely fine, it was a typo on my part: I intended to show all
manner of usage and processing of variables within the HEREDOC syntax.
However, in my own code, I generally include all variables between
{braces} when inside a HEREDOC block. Sheer preference for
readability in a large HEREDOC: because I don't normally use curly
braces around variables, when I see that on the page, I instantly
recognize that I'm still in the block (if all other clues miraculously
fail --- and we all know that they sometimes do).
