@ei-grad Thanks for your contribution.

Yes this feature only supported Go 1.7 and above. So we may have to limit this option. Let me have a look.

@ei-grad I have quick question for this PR.

To achieve this PR to work properly, following needs to be done:

• Please branch out fresh, since code quality improvements applied in master brach
• We have to take advantage of Go build constraints reference
• Create two files for type Request struct with definition for go1.7 & greater, go1.6 & below and implementation will be separate file which is common part
• And test cases accordingly

This approach is compatible with all Go versions.

Would you like like to try and send PR?

[ei-grad]

Yep, I'll do that :).
