What's wrong with var=$(</dev/stdin) to read stdin into a variable?

We've seen a few posts here lately that use this:

var=$(



in an attempt to read the shell's standard input into a variable.

That is however not the correct way to do it on Linux-based systems and Cygwin at least.

Why? What are the correct ways?
