# Add

Add behaves differently according to the type of the LHS:
* arrays: concatenate
* number scalars: arithmetic addition
* string scalars: concatenate

Use `+=` as append assign for things like increment. Note that `.a += .x` is equivalent to running `.a = .a + .x`.

Add is not (yet) supported for maps - however you can use merge `*` which will have a similar effect...
