What are you doing that triggers this error? I'm guessing that you have
an array A of substrings (a special string type that represents a portion
of another string; e.g. this is used for regular expression matches) and
you are trying to assign an ordinary string to A[i]. This fails because
there is (currently) no conversion method defined from other string types
to substrings.
If you want to make your array A able to hold arbitrary strings, not just
substrings, you should give it a type that can hold arbitrary strings.
e.g. if you are using a comprehension to define A, you could give it a type
A = String[] to say that A can hold arbitrary string objects.

Though we could define such a conversion method with:
convert{T:AbstractString}(::Type{SubString{T}}, s::AbstractString) =
let s′ = T(s); SubString(s′, 1, endof(s′)); end
Evan, what is your application here? What are you trying to do?

Steven,
The error is actually an issue with LightTable's Juno plugin and actually
has nothing to do with Julia.
I think what happened is in reporting the errors the plugin makes some
mistake and ended up reporting another error(or itself had some misuse of
strings) instead.
The actual error was discovered while running it from the command shell is
in fact:
ERROR: assertion failed
in ∫ at SimplePoly.jl:286
in ∫ at SimplePoly.jl:518
in ∫ at SimplePoly.jl:786
in ∫ at Factor.jl:153
which seems more reasonable, as the assertion is the one I wrote.
sorry for the troubles!

I'll try. the call chain is rather large and I'll see if I can get it down to a few constructs. On Tuesday, January 13, 2015 at 4:34:39 PM UTC-5, Steven G.
