Code like this:
pub fn push(&mut self, ch: char) {
if ch as u32 < 0x80 {
// ...Gives a parse error:
error: expected type, found `0x80`
if ch as u32 < 0x80 {
^~~~
Adding parentheses to disambiguate works around the issue:
pub fn push(&mut self, ch: char) {
if (ch as u32) < 0x80 {
// ...I understand that u32 is being parsed as a type and so < is assumed to be the start of type parameters. But maybe when that fails, the parser should backtrack and try to parse < as an operator?
