For a error thrown in some source location outside my control, is it possible to print the error object with **full precision, untruncated** , so that I can save the values from the REPL?

MWE:

```julia
julia> throw(DomainError(rand(100), "this is the problematic value"))
ERROR: DomainError with [0.885351, 0.310459, 0.494661, 0.470009, 0.52826, 0.0770669, 0.557097, 0.912992, 0.583488, 0.892067 … 0.873031, 0.357821, 0.0771776, 0.57399, 0.435096, 0.443316, 0.191378, 0.301983, 0.0455148, 0.515448]:
this is the problematic value

```

Can you catch the error?

```julia
julia> try
           throw(DomainError(rand(100), "this is the problematic value"))
       catch e
           e.val
       end
