Yes, because it interferes with syntaxes when comma is used for other 
purposes, such as separating elements of a list:

int x[] = {100,200,300,400};

Is that 4 elements, or the single number 100200300400?

But if the language doesn't provide some other way of separating digits, 
then sometimes you can provide something yourself:

int y = strtoint("100,200,300,400");

except it would be slower.
