It is a "must" in the actual version: the length? of tag exclude "<>" chars,
but form do not exclude them. Is the only exception in the any-string domain:
length? #a ;== 1
length? form #a;== 1
length? %a;== 1
length? form %a;== 1
length? <a>;== 1
length? form <a>;== 3
Replace must know the length of the formed version.
And: yes writing an full optimized version of replace is not a trivial task.
