Functionality of Python's range() in V

You cannot import this module via vpm
has my username as a Uppercase i.e. D
so it will complain about name error.
As a keen Pythonista I loved the idea of implementing range for V but I didn't like having to label the arguments. Here's an adaptation of your implementation using variable length args and generics. If you'd like to use it with credit, please do.

module range
pub fn range<T>(best ...T) []T {
mut begin, mut end, mut step := T(0), T(1), T(1)
mut arr := []T{}
match best.len {
1 {
end = best[0]
}
2 {
begin, end = best[0], best[1]
}
3 {
begin, end, step = best[0], best[1], best[2]
}
else {
eprintln('eprintln('Please input 1 to 3 integers or floats: range(start, stop, step)')')
exit(1)
}
}
if step == T(0) {
eprintln('range: step cannot be zero')
exit(1)
}
if (begin > end && step > T(0)) || (begin < end && step < T(0)) {
return []
}
if step > T(0) {
for i := begin; i < end; i += step {
arr << i
}
} else {
for i := begin; i > end; i += step {
arr << i
}
}
return arr
