Feature #18460: implicit self for .() syntax without rvalue

• Status: Rejected

[cvss (Kirill Vechera)]

We have a nice .() shorthand for calling Proc

m = 1.method(:+)
m.(2) # 3

But while we can use this shorthand in a Proc's context with the explicit self, we cannot use it with the implicit self:

m.instance_exec { self.(2) } # 3
m.instance_exec { .(2) } # syntax error, unexpected '.' (SyntaxError)

So I propose to make this syntax valid too.

• Status changed from Open to Rejected

This proposal is rejected for several reasons:

• we don't allow .m notation for implicit self (for now at least)
• You will gain only 4 fewer characters
• I don't think it's worth the cost of syntax complexity it brings
