#12041: fusion::traits for proxy types
 Reporter: jensweller@… | Owner: djowel
     Type: Feature Requests | Status: new
Milestone: To Be Determined | Component: fusion
  Version: Boost 1.61.0 | Severity: Problem
 Keywords: |
 This ticket has its origin in this thread:

 When working in generic code, one cannot determine if the underlying
 fusion::vector or other containers are containing a proxy type or not.

 E.g. fusion::result_of::at_c<Seq, I>::type requires an extra ::type, while
 this will likely error on normal fusion types. It would be nice to be able
 to seperate these by a enable_if into seperate methods.

 This is related to ADAPT_STRUCT and ADAPT_STRUCT_ADT usage, _ADT structs
 will result in using proxies in the type vectors.
