dump should add line numbers to code

EVAL => {} vs EVAL => ""

stay <safe> is the default. INPUT_IS_SAFE => 1

use the module that gives the eval code in the error

catch exception and let user check the object instead?
	$context->TryEval(...) ;
	
	$context->CaughtException()
		? $context->RethrowException()
		: $context->GetResults()
	
#variable in safe
	normal => ok
	shared => nok (access a package that safe chrooted
	persisten => ?
	eval_side persistent => ?

# "Give me sugar baby" Ash.

	variables can be
		shared
		shared reference
		persistant my variables

	eval side sharing
	
#Verbatim (scalar(definition) == 1) should have 2 arguments, second argument being 'VERBATIM'
	
#package cleanup after eval to free memory
	only if it is a default package
	
#use a random package by default

#accept FILE and LINE in Eval call
    use it as the file name concatenated with the object's name
