Question on how and should the Scala code change from => to ⇒ symbol?

[Henry Saputra]

Hi Mahout devs,

I am looking at the Mahout Scala code and some parts of the code use ⇒
symbol and some use =>.

I know we can use sacalriform to format the Scala code in sbt, but I
am not sure it is done with maven?
And also should we use ⇒ to represent => in Scala code for patches and
contributions?


Thanks,


- Henry
