multiple different errors for the same problem

[db48x]

src/comp/syntax/ext/qquote.rs:200:4: 200:16 error: this function takes 2 parameters but 1 parameter was supplied
src/comp/syntax/ext/qquote.rs:200 iter::each() {|ch|
^~~~~~~~~~~~
src/comp/syntax/ext/qquote.rs:200:4: 200:14 error: could not determine a type for a bounded type parameter
src/comp/syntax/ext/qquote.rs:200 iter::each() {|ch|
^~~~~~~~~~

Looks to me like the second error is useless.

Also see #1871

[db48x]

Yea. Of course, the spans aren't exactly the same.

Fix for #1871 should fix this, but I'll make sure it does.

I don't know what code brought up this error, but the fix I'm working on for #1871 should address it. Reopen if you have a specific example that provokes multiple errors. Thanks!
