followed by a semicolon.
This allows code like `vec![1i, 2, 3].len();` to work.
This breaks code that uses macros as statements without putting
semicolons after them, such as:
fn main() {
...
assert!(a == b)
assert!(c == d)
println(...);
}
It also breaks code that uses macros as items without semicolons:
local_data_key!(foo)
fn main() {
println("hello world")
}
Add semicolons to fix this code. Those two examples can be fixed as
follows:
fn main() {
...
assert!(a == b);
assert!(c == d);
println(...);
}
local_data_key!(foo);
fn main() {
println("hello world")
}
RFC #378.
Closes #18635.

register_diagnostic! { E0001, r##"

This error suggests that the expression arm corresponding to the noted pattern
|
|
will never be reached as for all possible values of the expression being matched,
|
|
one of the preceeding patterns will match.
|
|
|
|
This means that perhaps some of the preceeding patterns are too general, this
|
|
one is too specific or the ordering is incorrect.
