  template <- 'type {{type}}: {{uppercase}},{{lowercase}}'
  whisker_mapply( template, list(type="alphabet"), lowercase=letters[1:3], uppercase=LETTERS[1:3] )
  
  # USED IN LOOP ... 
  #  template is pre-defined at top of code (above) and is not changes, 
  #   nor is it required to modify data. This is handled seemlessly. 
  ## Not run: 
  # for( type in 1:2 ) { 
  #   print( whisker_mapply( template, list(type=type, uppercase="A"), lowercase=letters[1:3] ) )
  # }
  # 
## End(Not run)
