I hear what you're saying, and I neither agree nor disagree. But
describing it as "Type A" versus "Type B" exaggerates the difference. Its
more like "Type A" versus "Optional Type A" -- and, so the argument goes,
it ought to be blindingly obvious from context.

And that is why we all hold COBOL up as the paragon of excellence for a
programming language! *wink*
Or if you don't like COBOL, how about Hypertalk?
put 42 into x
ask file "Which file would you like to open?" with "default.txt"
if it is empty exit to Hypercard
put it into thefile
open file thefile
repeat with num = 1 to x
write "spam" to file thefile
close file thefile
