If (assuming from them being called lambdas) they are primarily for
small functions without side-effects then it's already a significantly
stronger specification than what we have right now with C nested
functions. That would end up enforcing what you de

Why? The syntax doesn't seem to be something unexpected, and as C doesn't
have lambdas, one can use the nested functions instead.
The only problem is if you need to pass function pointers somewhere else
(and target doesn't have function descriptors or so

I am relatively sure C will get some form of nest

I do not really agree with that. Nested functions can substantially
