Questions about styles, classes, new shape syntax

[muteboy]

I have a node defined as follows: decision_Review@{shape: hex, label: Review. OK?}. This draws a hexagon with the label "Review. OK?"

I can also define a class for decision nodes: classDef decision fill:Green,stroke:Blue,stroke-width:4px;

I can apply this class to the node like this: decision_Review:::decision@{shape: hex, label: Review. OK?}. This works.

Question: Is it possible to include the shape definition in the class definition? Then I could just use something like: decision_Review:::decision@{label: Review. OK?}

Question: Is there a simpler syntax to create a node, give it a label, and then rely on class styling to give it the shape, color etc?

I can also supposedly use class decision_Review decision; to apply the class to the node, but this doesn't seem to work - unless I put this AFTER the node creation.

Question/Suggestion: It would be very nice if I could use a wildcard to assign classes to nodes, like this: class decision_* decision;, which would assign "decision" to all nodes starting with "decision_"
