Hi all,
I'm currently looking for a way to say something like "create this resource if
it doesn't already exist". The current way to do this, is simply checking with
<pre>if ! defined(Resource['$resname']) { resource{ '$resname':; } }</pre>
which works with strings, but doesn't support arrays. And I'm running into
several cases in which it would save me a lot of work if I could make this work
if $resname is an array. I think more people can do something useful with this
kind of functionality.
Although you probably have a better idea what would fit, a syntax that would
work for this is something like
<pre>?resource { '$resname':; }</pre>
Would be especially useful if it could also support virtual/exported resources,
like so, for example:
<pre>?@@resource { '$resname':; }</pre>
Thanks in advance for considering this!
