#5790 closed Bugs (fixed)

call_traits::param_type generates const references for enums

Reported by: defaultryan+boost@… Owned by: John Maddock
Milestone: To Be Determined Component: call_traits
Version: Boost 1.47.0 Severity: Problem
Keywords: param_type enum is_enum Cc:

Description

call_traits<SomeEnum>::param_type currently evaluates to "const SomeEnum&" instead of "const SomeEnum".

Seems that since call_traits is using is_arithmetic to funnel down into ct_imp2<T, true>, we could also use is_enum to send us down the same path and get the desired behavior.

More specifically, change line 82 from 

::boost::is_arithmetic<T>::value

to 

::boost::is_arithmetic<T>::value || ::boost::is_enum<T>::value
