[J3] Consistency in conversion functions

Hi,

My $0.02

The proposed COMPLEX was to eliminate the appearance
of an uglifying kind type parameter.  While small, this is good.

This appears to have been overtaken by having a programmer-settable
default kind per intrinsic type per scope.

I would be surprised if gfortran implemented that proposal.  If the committee chooses to add a COMPLEX intrinsic, someone should determine what gfortran does.

I don't recall that I had any issues with the proposal, but I was still learning standards issues. I don't recall what the objections to it were then, but I would be inclined to support it for 202Y.
