Expanding let $ident:$ty = $expr;

[tathanhdinh]

Hello all,

Currently, if_chain refuses to expand the pattern let $ident:$ty = $expr;, for example this piece of code

if_chain! {
  if false;
  let y: u32 = 4;

  then {
    ...
  } else {
    ...
  }
};

will not compile. I try to add a rule to support this pattern as:

(@expand $other:block let $ident:ident:$ty:ty = $expr:expr; $($tt:tt)+) => {
  let $ident:$ty = $expr;
  __if_chain! { @expand $other $($tt)+ }
};

but I don't know whether there is a better way to do that or if_chain is interested in supporting this pattern.

Many thanks for any comment.

Can we please have a new release with this fixed?
