Elementwise operations
Hi,

I seem to be having difficulties with the element-wise operations, in particular the `==.` operator.
For any comparison operators postfixed with '.', the error message reads "undeclared identifier".

The `.==' operator works, but only for tensor to tensor comparisons.
I cannot get any tensor to scalar comparisons to compute.

Installed via nimble, github pull, on nim-1.2.4.

Many thanks for your help


Example:
nim> echo t >. int(1)
Error: undeclared identifier: '>.'

nim> echo t
Tensor[system.int] of shape [6]" on backend "Cpu"
	0	1	2	3	4	5
