Find a way to get source excerpts for REPL code?

[topolarity]

julia> @check_allocs foo() = rand(Any[1,1.0]) + true
julia> try foo() catch e e.errors[end] end
Dynamic dispatch in ./REPL[2]:1
  | (source not available)
Stacktrace:
 [1] var"##foo#225"()
   @ Main ./REPL[2]:1

For dynamic dispatches especially, this source information is pretty important.

I believe CodeTracking.jl already support this with @code_expr and @code_string.
