difficult to parse error

[aviks]

If I pass in an Any[] array to SampleBuf, even if it contains all floats, it throws an error that does not mean much to me. This error goes away if the array is typed as Float64[]

s =  SampleBuf(x, 44100.)
44100-frame, 1-channel SampleBuf{Any, 1}
1.0s sampled at 44100.0HzError showing value of type SampleBuf{Any, 1}:
