[perl #126827] [BUG] Class declaration from one module not visible if another module is loaded after it with a very similar class declaration in Rakudo

[Carl Mäsak via RT]

<nine> masak: I still doubt it's actually 8728828 that's to blame. Between 
3b943782 and 8728828 there's a lot of refactoring, especially some changes 
touching the handling of global merging. Might be a good idea to bisect that 
(with manual precompilation in every step)
<masak> nine: will do.

<masak> nine: the results are in. a bisect of 3b943782^..87288285f, with 
precompilation at every step, turned up 87288285f as the first bad commit.
