I love it. Living proof that languages doesn't need forced types.

Data is Data. It's kinda object programming as visioned in the 70".

So easy and trivial language.

It depends on the use case. For instance you open a socket, write there any value you have without serialization, read it in the other side, data transfer done.

It's only the interface that is of a string. An array is a list of strings with space between, but only for the programmer. The runtime is free to use an actual array.
