glad to hear that.  yes, the resemblance to variables syntax is a mixed

pro: it's easier to recognise magic sequences in the string.
con: it's easier to mix up the two syntaxes.

I think cons. outweigh pros. in this case. Somebody can forget to use 
':' after hex, etc.

we have three proposals here:


and a slightly more nebulous "a more unique prefix", perhaps this


that would be fine with me, in any case.

I want to note that a syntax mix-up can be flagged at upload time, so I
don't think it's a big problem in practice.

this is not entirely correct, a typo like ${hex.ff} can only be flagged
if "variables" is in use, otherwise it will be used verbatim.

this was a bit lazy editting on my part.  I made the argument for the
reinstating of status quo in a different thread, so please ignore the
removal here.

So I will argue in another thread ;-).

you haven't done so yet :-)  it may have been lost in the long thread,
I'll repost my suggestion in a new thread.
