Can we add alias for `auto-expansion TypeTuple` and add link
to the previous documentation like this:
alias ExpandedTemplateArgumentList(T) =
TemplateArgumentList!(T).expand;
It looks like it can fix all objections here.
What is this supposed to give over just using .expand
directly? I have not seen a good rationale that justifies it
among existing objections, probably have missed it.
It allows doing a simple
's/TypeTuple/ExpandedTemplateArgumentList/'
Using "TemplateArgumentList!(T).expand" is a "much" more
involved transition: It's not just a simple rename.
%s/TypeTuple!(\([^)]*\))/TemplateArgumentList!(\1).expand/g ? :)
Yes it will fail for few cases where there is a string with ")"
among parameters, but same applies to
s/TypeTuple/ExpandedTemplateArgumentList/; it still is a simple
rename
Though algorithms in std.typetuple are supposed to be changed to
have interface based on paced one when copied to std.meta.* so in
practice it will be just s/TypeTuple/TemplateArgumentList/
Even if user attention will be needed to every single use point
(which is not true), it is not justified enough objection - this
is what deprecation process is for. No silent breakage is
possible and this is only thing that really matters in this
context.
