Consider this code:
https://github.com/muellan/clipp/blob/master/examples/options.cpp#L23
Here's the code for context:
auto cli = (
option("-a").set(a) % "activates a",
option("-b").set(b) % "activates b",
option("-c", "--noc").set(c,false) % "deactivates c",
option("--hi")([]{cout << "hi!\n";}) % "says hi");Effectively what we have here is:
auto cli = (expr1, expr2, expr3, expr4);
This generates the following level 1 compiler warning under visual C++ for example:
warning C4548: expression before comma has no effect; expected expression with side-effect
I assume this is just an oversight in the examples?
So, is there any advice on the correct way to initialize a group from a set of options?
