While loop feature discussion

[ghost]

1. First of all, I do not think that the unofficial ï and ; s are useful for code-golfing. Do you think so? (I will make a PR to revert these changes if that's a yes.) (I am adding the Ẹ command to represent exponentation.)

2. (Debatable) I think that the implicit while loop condition 1 is too challenging to golf for a Keg program. E.g. this highly-golfed Truth-machine:

   :[{:.

   If the condition is the top of the stack, then the program will be:

   :{:.

   However, some challenges require explicit infinite loops, and the current while loop is useful for these:

   {

   If the condition is the top of the stack, then the loop has to be:

   1{

Do you want to keep or change the while loop condition?

1. Keep the ï and ; command just in case they are needed.
2. I believe that keeping 1 as the while loop condition would be best as some challenges (e.g. * interpreter) require it.
