@async / let block scope issue

[vtjnash]

the @async block is creating a new variable instead of capturing the intended one from the let block (due to the presence of a global of the same name)

julia> t = 3
3

julia> let t
           c = Condition()
           task = @async begin
               notify(c)
               t = Timer(0.055)
               wait(t)
           end
           wait(task)
           println(t)
       end
ERROR: UndefVarError: t not defined
 in eval(::Module, ::Any) at ./boot.jl:243

Shouldn't the let statement be let t=t? With that change the above code block works fine.

But the issue raised by you seems similar to #14399
