Would that remark still apply if Excel had - let's say - a function
MINVERSE() - a similar single line of code?

Well, interestingly, I do believe it does.

Have a look at eg
http://www.chem.mtu.edu/~tbco/cm3450/Excel_Array_Formulas.pdf

I suspect people don't realise what power Excel has, because hardly
anyone talks about it. They either talk about everyday corporate number
crunching or conventional programming lnaguages. Few people think about
taking Excel's components and mixing them together to solve
simultanaeous linear equations.
