Bug Description

I frequently get these sorts of errors, where claude has put escapes before exclamation marks ! in code it's written out

     error: unknown start of token: \
      --> macro_test.rs:6:16
       |
     6 |         println\!("Stringified value: {}", stringify\!($value));
       |                ^

     error: unknown start of token: \
      --> macro_test.rs:6:53
       |
     6 |         println\!("Stringified value: {}", stringify\!($value));
       |                                                     ^

is there some intended escaping of !? would it be possible to try to help it work out when to use escapes?
