Hi all -

Have been playing with the Power conjunction using this (not uncommon) example

   po2=. 3 : '+:^:y 1'   NB. power of two by repeated doubling
   po2 5
32

Then I have wanted to come up with a tacit version of *po2 (a monad with no of repetions as only argument) and tried

   (+:^:])5   NB. does the doubling alright but  ...
160

and a number of variations of this

   (+:^:] 1)5
|syntax error
|       (+:^:]1)5

Q: Where should I put the start value of 1..?

Thanks
-M
