when-let is not destructuring. let-alias is very limited -- 
destructuring only for one type.
What I meant is there are similar constructs in functional languages 
like ML/Haskell which have also been available lately in 
Python/Ruby/Rust, that allow both matching and getting the data out in 
the same construct, accepting many or all data types available in the 
language.
pcase is an implementation of that idea. Perhaps it looks a bit cryptic, 
but I'm not sure what better syntax it would have in Lisp, while 
retaining the same capabilities.

Perhaps (info "(elisp) pcase Macro") will help?
