Data Structures advanced
Structured Concurrency
PHP 8.1+
A model where child tasks live inside a parent scope that waits for all of them to finish before it exits, so no task is ever orphaned.

Symbol Table Resolution
PHP 5.3+
The compiler phase that maps identifiers (variables, functions, classes) to their declarations, scopes, and types during semantic analysis.

Compiler advanced
Escape Analysis
A compiler optimisation that determines whether an object's lifetime escapes its allocating scope, enabling stack allocation or full elimination of heap allocations.

Python Descriptor Protocol
Python 3.6+

Regex Conditional Patterns
PHP 4.0+

Regex advanced
Forward Secrecy
PHP 7.4+
A key-exchange property where ephemeral session keys are discarded after use, so a future compromise of long-term keys cannot decrypt past sessions.
