Please also be aware that when resuming from a paragraph, Anselme will try to restore the interpreter state as if the function was correctly executed from the start up to this paragraph. This includes:
* if the paragraph is in a expression block, it will assume the expression was true (but will not re-evaluate it)
* if the paragraph is in a choice block, it will assume this choice was selected (but will not re-evaluate any of the choices from the same choice group)
* will try to re-add every tag from parent lines; this require Anselme to re-evaluate every tag line and decorator that's a parent of the paragraph in the function. Be careful if your tag expressions have side-effects.
