Except operation in WDL

It seems that Workflow Definition Language is missing the Except operation. Please add this as its critical when comparing two arrays. 

See this post for an example of Except that is missing: https://powerusers.microsoft.com/t5/Building-Flows/Comparing-Two-Lists-and-Finding-Differences/m-p/1...

Thank you

Please can we have this implemented as we have the other 2 array actions that are really helpful, except is really needed and shouldn't be too hard to implement!

 

Thanking you much!

Hi there,

 

I believe it is possible to perform an except action on two arrays using the select action.  Please take a look at my video here

 

I would be interested to hear if this helps you at all?

 

Cheers
