A linear algebra library is more than matrix multiplication. For example 
operator precedence should work as expected. Allowing users to write correct 
code is more important than speed.
    
    
    import arraymancer
    let
      x = toTensor(@[3, 3, 3, 3, 3])
      y = toTensor(@[2, 2, 2, 2, 2])
      z = toTensor(@[1, 1, 1, 1, 1])
    
    echo x .* z + y
    
    
    Run

Results in 9s instead of 5. If only you weren't **obsessed** with performance 
you would [see](https://irclogs.nim-lang.org/21-10-2019.html#06:12:13) the 
issue.

...and while other community members try to be helpful and provide 
[suggestions](https://irclogs.nim-lang.org/20-10-2019.html#16:51:57) others 
choose to show off in every thread and every chat. Enough said.
