String prompt pasting

[diegozea]

Hi!

I have just notice that Julia errors when prompt pasting a String. It can not realize that the second string is the output of the first one, and tries to uses the first one as the docstring of the second:

julia> "String"
"String"

I have found this on:

Julia Version 1.6.2
Commit 1b93d53fc4 (2021-07-14 15:36 UTC)
Platform Info:
  OS: Linux (x86_64-pc-linux-gnu)
  CPU: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-11.0.1 (ORCJIT, skylake)

Best,

P.S. It works fine in Pluto:

julia> value = 2 + 2
4

julia> "Result: $value"
"Result: 4"

Was also observed in #17599 (comment).

The way the prompt paste work is that as much as possible that is valid to parse gets parsed, the rest gets discarded. So if you paste

julia> 1+1
       errorerror

it will just execute 1+1. Since

"String"
"String"

is valid syntax, that is what will be used. I guess this could be solved explicitly looking for this scenario.
