No such method 'gist' for invocant of type 'BOOTSTRAPATTR'
in method gist at src/gen/m-CORE.setting:7733
in sub say at src/gen/m-CORE.setting:15838
in block <unit> at ./bug.p6:3
the result is the same if Str is replaced with a literal string or Int
Hi,
I can tell you why this doesn't work and why it maybe shouldn't:
Str is a class that's needed extremely early in the build process, so we
create it in the "bootstrap" phase. The regular Attribute class isn't
available there, yet. That's why we use BOOTSTRAPATTR instead. That one
doesn't have a gist method to pretty-print itself.
However, what it does have (and has to have) is a "name" method. So this
code works fine:
#!/usr/bin/env perl6
use v6;
.name.say for Str.^attributes;
