Bad error message

[IainNZ]

using JuMP
function test(N)
  m = Model()
  @defVar(m, x[-5N:5N])
end
test(1)

ERROR: Currently only ranges with integer compile-time starting values are allowed as index sets. -5N is not an integer in range -5N:5N.

[IainNZ]

Also,

function test(N)
  m = Model()
  @defVar(m, x[[-5*N:5*N]])
end

works fine

[joehuchette]

Maybe we can implicitly turn @defVar(m, x[-5N:5N]) into @defVar(m, x[[-5N:5N]])?

[IainNZ]

Something is wrong, because 1:5N is ok but -5N:5N isn't

[joehuchette]

The error is alluding as to that though, -5N isn't an integer value known at compile-time. It could be a bit clearer, and hopefully we can remove that restriction entirely.

This is fixed by #192

Oh good
