Ruby.DL and FFI libraries are great for programmers like me who are not internet programmers, but are more interested in scientific and number processing etc.

[ruby-core:28419] [Bug #1983](Rejected) Struct doesn't define instance methods for valid method names

From: Yusuke Endoh <redmine@...>
Date: 2010-03-02 13:42:07 UTC
List: ruby-core #28419
Issue #1983 has been updated by Yusuke Endoh.

Status changed from Open to Rejected

Hi Jeremy,

> By why not generate the reader and skip the setter, then?

In [ruby-core:4404], matz decided to prohibit such a field name once.
And in [ruby-core:4577], he relaxed the restriction:

> having field names with "?" can be valid if field
> accessor is disabled for such cases.

So it is currently intended, not a bug.  I close this ticket.


You can re-register this as Feature ticket.
If you do, please elaborate the motivation example.


> I'd like attr_reader :foo? to work too. It's a common convention for booleans.

We cannot define @foo? even by using reflection:

  instance_variable_set(:"@foo?", 42)
    #=> `@foo?' is not allowed as an instance variable name (NameError)

It is never a common convention.


IMO, if such a field name is allowed, we would next want to use foo?=
and @foo?.  I think Ruby design is sane because it limits ourselves
from such earthly desires.
