Types from identifiers
======================
Here's a way of "manually inferring" the type from identifiers. It can be
useful if identical identifier declarations appear over and over again.
autotype token = Token
autotype x = int
autotype y = int
autotype input = InputStream
autotype p0 = [2]int
autotype p1 = [2]int
func sum(x, y) -> int
{
return x + y
}
func parse(arena, input)
{
...
ref token = .next_from_stream(input)
...
}
func calculate_location(p0, x)
{
# no point in abbreviating built-in types such as "int" to "let"
int y
...
[] p1 = [1,2]
...
}
