[ruby-core:81554] [Ruby trunk Bug#13623] meta-programming, adding sub-module fails with syntax error

[adriaan1@gmail.com]

Issue #13623 has been updated by caschip (Aad Schippers).


So you are saying this is how it should work and not a bug? If that is true, I should close this. What do you mean when you say that Object::const_get('Foo')::Bar is syntactically a constant. Its contains characters that are not appropriate in constant names, like brackets and single quotes, and a method is called, const_get, to evaluate it. To me it is an expression a::b::c with two scope operators, two constants (Object and Bar) and one method call that returns a constant const_get('Foo') => Foo.

----------------------------------------
The goal is to add a sub-module to a higher level module. The higher level module is derived from its name in a string. This works in one case and gives an unexpected syntax error in another case.

failing_meta:4: syntax error, unexpected '\n', expecting &. or :: or '[' or '.'
failing_meta:8: syntax error, unexpected keyword_end, expecting end-of-input
