documentation: corrected example for parameter injection

[rbock]

Hi,

See https://github.com/lock3/meta/wiki/Metaprogramming-Introductory-Tutorial#parameter-injection

The code sample does not work any more, because

• set_name is now set_new_name
• fragment should be fragment struct (it does not compile without struct)

Also, it might be good to show off the return_type_ofmeta function :-)

Updated version: https://cppx.godbolt.org/z/Kr6sT9

Best,

Roland

:grimacing: whoops, fixed, thanks!

Noted, I'll try to keep that in mind for a future example :)
