Just spotted something in the logs:

m: role R { }; &R
rakudo-moar e9351cbaa: OUTPUT: «=== SORRY!===  Error while compiling <tmp>␤Illegally post-declared type:␤ R used at line 1␤␤»

The user erroneously was prepending & to a role name while trying to call .WHAT.say on it and it was giving that error.

Don't know what the right behaviour/error should be, but at the very least the error claims something is post-declared, yet in the code it's pre-declared.

Note that there is similar behaviour for classes as well.

> class T { }; &T
===SORRY!=== Error while compiling:
Illegally post-declared type:
   T used at line 1
