I've certainly seen suggestions for lambdas in C.  I'm not sure that it 
is a great idea to add such high-level features to C - if we want to 
work in C but with lambdas, C++ already supports that.  But "blocks" 
(borrowed from Objective-C, IIRC) are more advanced than gcc's statement 
expressions, so I suppose lambdas are a reasonable superset of these 
three extensions.
