CallMode

Function calls with commas and parentheses? Blasphemy. Call Mode is here to help you break free.

Activate Call Mode in the REPL with a closing parenthesis, ), symbolizing the end of our bond with the obsolete legacy syntax.

julia> using CallMode

julia> mapreduce(abs2, +, 1:5; init=1) # clunky and verbose
56

@call> mapreduce abs2 Base.:+ 1:5 init=1 # clean and pure
56

A qualified Base.:+ is necessary, as abs2 + 1:5 would be parsed as (abs2 + 1):5. One could alternatively use (+), at the cost of using parentheses — ew.

The package also exports the @call macro, in case you don't even want to use ) to activate Call Mode:

julia> @call mapreduce abs2 Base.:+ 1:5 init=1
56

And you can rest assured knowing that the package source code uses no parentheses.

To hell with parentheses!
