[rbond] observing blocks? #9

Closed xkrogen closed 8 years ago

xkrogen commented 8 years ago

In Ruby, it's pretty common to pass a block as an argument to a method. Should we include this in our observation? If so, how? The blocks can be pretty important to the program's execution but I see no easy way to include them in observations.

Are you thinking of spying the blocks as data, or with spy_points (as methods to be spied)? The former does not make sense, for the latter you can do if you name it.

This passing-blocks style is called higher-order programming and it is just a different way to organize the flow of control. Bond is for spying the first-order data values, not the higher-order ones. Even in Python you would not spy the lambdas.

I was thinking the former, but yeah, I suppose you're right that it doesn't really make sense. Nevermind.
