/The/ matrix multiplication operator?
In which language? And what was wrong with "*"?
It seems you're unaware that Python *already* has an '@'
operator. It was added specifically so that numpy could
use it for matrix multiplication. A new operator was
needed because numpy already uses '*' for elementwise
multiplication.
So, the issue with @ being mistakenly marked up already
exists.
(I've implemented matrix multiply in a language (although for
specialised matrix types), and I used the same "*" symbol as was used to
multiply anything else.)
Before '@' was added, numpy did this as well, but it
was a pain to have to use a whole different type just to
get one operator to behave differently. Painful enough
that Guido was eventually persuaded to add a new operator.
