For the section on lambdas: There's a better way than using  
llvm.frameaddress: move all the locals used in the lambda in a struct (and  
make the container function use that structs values instead of a regular  
local), then pass the address of the struct to the lambda as a "this".  
This is how objc for example passes things to a block (although objc does  
ref counting in addition to that so the block can be used after the  
original returned)
