How to specify a read-only array to jit?

[it...@esss.co]

I can't find a way to write a function signature that takes a read-only array without doing some workaround like:

a=numpy.zeros((1,1))
a.flags.writeable=False

numba.jit(void(typeof(a)),nopython=True)
def foo(a):
    print(a)

Any ideas on how to do it without the dummy variable 'a'?

Think you can do this with the `types.Array` constructor like this:

from numba import jit, types

@numba.jit(types.void(types.Array(types.float64, 2, 'C', readonly=True)), nopython=True)
def foo(a):
    print(a)

which will give a signature:

[(readonly array(float64, 2d, C),)]

Hope this helps?

Thanks,
