Yes, I would. Somehow there's a difference between user input and
program code. For user input, you want to be pretty permissive in what
you accept. I guess you could force the programmer to write
try
float_of_string str
with
Failure _ ->
int_of_string str
but there's all sorts of corner cases in that, from alternate bases to
range issues.
But technically it's a violation of spec, as the note (that I missed
before) in the float-literal definition about requiring either an
exponent or a decimal part of the number should apply here too.
