[fpc-devel] Proposal/discussion: Simple nested functions and 'outlining'

In a way, yes, but not quite the same, since multiple calls to the 
nested function would still redirect to the same block of code rather 
than being inlined at each call.  I suppose more similar to the old 
GOSUB; RETURN combination in old versions of Basic, and the nested 
routine slotted either at the end of the parent function or, if the 
compiler is intelligent enough, right after one of the function calls 
(in effect, inlining it at this point) so the peephole optimizer can 
then remove a zero-distance jump.
