Hello. I have a script that contains the following line:

```
A[k+1:n,k+1:n] -= A[k+1:n,k] * A[k,k+1:n]
```

where *k* and *n* are integers and the values in the two-dimensional array are floats. Previously, in Julia 0.4.6, this was no problem and I achieved the results I desired with no errors. However, in 0.5.0, I get an error

```
ERROR: MethodError: no method matching *(::Array{Float64,1}, ::Array{Float64,1})
```

along with a lot of text referencing closest candidates. Has something fundamentally changed in Julia 0.5.0 that no longer allows this? How may this be rectified?

Please let me know if my entire script is needed to understand the issue more fully.

Thank you.
