It needs to be a reference. Otherwise, you store the entire
stack frame in the struct? That wouldn't be a "field". It also
has write access to the context:
Why not just capture the variables that are actually been
referenced? Also being a field doesn't put limits on the size of
the "field".
I like how C++ lambda lets you choose what variables to capture,
and how are they captured. I'm little disappointed that D doesn't
let me do the same.
