I am using ESS 18.10 with some recent version of julia 1.7.0-DEV.894 (2021-04-09) and I encounter the following weird behavior.
julia> let P = 10 P end
let P = 10 C-c C-c
With a multiline let form, the first line is evaluated, returned then the repl hangs. Other multilines expressions do not exhibit the same behavior.
julia> a = 3 b = 2 a+b
a = 3 3 julia> b = 2 2 julia> a+b 5
Is there a quick fix? Does julia 1.6 have the same problem? I switched directly from 1.1 to 1.7.
