sad - but its still very young feature :)

im using something like an description on my methods to describe 
parameter "features" for an resource manager - something like "read", 
"write", "copy", "read_write" etc.

to have this at compiletime available by using UDAs on parameters  + an 
compiletime generator would be absolutely briliant

my vote +1 for UDAs on parameters
