Possible to get better error message on syntax errors?

[KristofferC]

This is what I get from Revise on a syntax error:

┌ Error: Failed to revise /home/kc/JuliaPkgs/SIMD.jl/src/simdvec.jl
│   exception =
│    LoadError: "missing comma or } in argument list"
│    Stacktrace:
│     [1] parse_source!(::OrderedCollections.OrderedDict{Module,OrderedCollections.OrderedDict{Revise.RelocatableExpr,Union{Nothing, Array{Any,1}}}}, ::String, ::String, ::Module) at /home/kc/.julia/packages/Revise/S7mrl/src/parsing.jl:45
│    in expression starting at /home/kc/JuliaPkgs/SIMD.jl/src/simdvec.jl:3

Restarting Julia and trying to load the package gives:

ERROR: LoadError: LoadError: syntax: missing comma or } in argument list
Stacktrace:

What I am interested in is of course /home/kc/JuliaPkgs/SIMD.jl/src/simdvec.jl:256. It would be nice if that information could somehow be made available.

Do you have a reproducer? I almost always get the line number.

Sure, in the branch at eschnett/SIMD.jl#63, I go into simdvec.jl and on line 137 I write function then I trigger a Revise and get (sorry about unicode mess):

julia> Revise.revise()
