Traits with lifetimes fail to compile about sealed-rs

[jmg-duarte]

Hello, I'm glad you reported this issue! Could you provide the cargo expand output?

@WilliamVenner I have a fix for your issue in particular but I'd like a better example to solidify the implementation.
If you could submit one, it would be great!

The issue is that here only type_params are forwarded, not lifetimes or const generic params:

sealed-rs/src/lib.rs

Lines 157 to 159 in aea9c3d

	item_trait
	.supertraits
	.push(parse_quote!( #seal::Sealed <#(#type_params, )*> ));

The fix (#13) is to use let (_, ty_generics, _) = trait_generics.split_for_impl(); and #seal::Sealed #ty_generics which includes all three types of params together.
