Nim 2 feature request - Custom operators

[elcritch]

TIL you can do infix unicode operators! Just one 
`--experimental:unicodeOperators` away. Then you can define an appropriate 
unicode operator like say "⊘":
    
    
    proc `⊘`(a, b: int): int = a + b
    1 ⊘ 2
    
    
    Run

Though editor support for Julia includes converting pseudo-latex names into 
unicode operators like `\kronecker` => `⊗`.
