1192,[RFE] Redesign Parrot NCI callback functionality,japhb,,"This is a migration of RT #50360; original text follows:

Parrot's NCI callback subsystem design will not work (and cannot be
directly extended) for callbacks that do not carry an opaque user data pointer. Many existing callback-based APIs do not fit this description, including certain GUI toolkits such as GLUT.

Allison and others have brainstormed a few possible ideas, but none was fleshed out to the point of being implementable. The following threads on the parrot-porters mailing list covered part of this:

Also, I've attached some IRC discussion of this (slightly edited as per participant's request).
