^^ "B"{link: Index} {section: B}
* _backtracking_ {section: backtracking} - after a part of a pattern didn't match, this last operation might not be counted (undone) and the pointer for the position in the string where actual matching is taking place is going a few steps to the left (it goes back)
* _"binding"{link: [Perl 6 Variable Tablet] Binding}_ {section: binding} - making two variables share the same content by pointing to same memory location

^^ "C"{link: Index} {section: C}
* _closure_ {section: closure} - routines whose state (content of all local variables) is completely preserved until the next execution, mostly used as a fancy alias for a _"block"{link: block}_
* _coderef_ {section: coderef} - reference (pointer) to an executable block of code (routine)
* _compilation_ - reading the human written source code and make it an executable (piece of) program
* _compile time_ {section: compile time} - time when Perl converts source code to executable form (bytecode), is always before _"runtime"{link: runtime}_ even if code can be compiled via *"eval"{link: eval}* and *"evalfile"{link: evalfile}* when the program is * _context_ {section: context} - when executing a function or operator Perl considers the expression from which the call was to return a "scalar"{link: [Perl 6 Index Tablet] scalar type} or other kind of result
* _context variable_ {section: context variable} - name for *"$_"{link: context var}*, which is used by built in Perl functions as an implicit parameter and as memory of the last result
