Request macros can not accept mixed field definitions (with and without aliases) #41
Description
It would be nice, if we could mix fields with aliases (field_name as (field_alias): ...) and without aliases (field_name: ...) in the same request! or request_ref! macro invocation.
The problem is fields definition block in the macros is not homogeneous, because I can't use incremental TT muncher pattern, as macro calls doesn't work inside struct definitions, and I have to put macro call inside struct to unroll heterogeneous fields pattern.
