Sorry for this probably naive question. I was trying the following:

import vmath
var a = vec2(10.0,2.0)
echo a.len

This works if compiled with -d:vmathArrayBased, but how can I get the length of the vector when is not based in arrays?

    You can use the length() function to get the magnitude:

    Or do want to get how many dementions the vector has? In this case 2 because its a vec2?

    Yes, I meant getting the vector dimension (2 for Vec2). I think it would make sense having an equivalent len for the cases where is not compiled with -d:vmathArrayBased.

    Thank you for this issue. I actually have a need for this feature, and so I added it here: #87
