Yeah, they seem to be a bit more trustworthy to some extent.

I tried looking into how isArray is defined. Like, does being 
able to index mean it's an array, or are these only static &/or 
dynamic arrays? Though I couldn't understand the sourcecode.
Hence I just use(d) `is(typeof(variable[0]))` and 
`is(typeof(variable[0][0]))`.
