[Cs3] lambda caption by const reference

[Mikhail Nesterenko]

CS3 students,

lambda caption by const reference is not available as an explicit
construct. However, if there is a constant in the contents, and it is
being explicitly captured by reference, it becomes a const reference
capture. For example

....
cont int i=55;

...[&]{i++;}; // not allowed: i is captured by reference and then modified.

thanks,
