DynamicBindingVsLexicalBinding

[Andreas Röhler]

Hi,

in article

http://www.emacswiki.org/emacs/DynamicBindingVsLexicalBinding

it's said WRT lexical binding

"Because it's (1) much easier for the user [that is, programmer], because
it eliminates the problem of which variables lambda-expressions use
(when they attempt to use variables from their surrounding context)"

Unfortunately couldn't find a use-case where it is easier - while consenting it 
might be easier for the compiler to swallow.

Could someone give an example, where lexical binding makes coding easier?

TIA,

Andreas
