Re: [elixir-core:8007] Add <*> to the list of parseable operators

2018-05-17 Thread Michał Muskała 
I wonder if it would make sense to have a whole suite of <_> wrapped math 
operators. I could imagine, for example, the Decimal library implementing them 
and you could import to the decimal calculations easily without sacrificing the 
regular math operators.

Michał.

Re: [elixir-core:8007] Add <*> to the list of parseable operators

Many thanks!

Should I open an issue on GitHub or something?

 Hello!

 I'am developing a matrix manipulation library for Elixir (
 https://github.com/versilov/matrex)
 and it would be really nice to have <*> operator, so that it could be 
 overriden for matrices dot product (or element-wise multiplication).

 Is it possible to add it?
