Quick question about $ variables

[stefan.paetow at diamond.ac.uk]

Hi all,

I've been looking at using ${...} variables wherever I can and so far it's been relatively successful. The only place where I am stuck is using some comparisons, e.g.

if ("%{Attribute}" == "${variable}") {
  ...
}

The Attribute portion expands, the $-variable part does not (although it is in double-quotes as per the unlang documentation). Quoting the literal value of the variable works.

Am I correct in saying that this is not supported? Just asking so I know how far I can push this :-)
