<div>I think functions based on pipes makes a simpler feature, as well as allows for use in interactive sessions, resembling Bourne-compatible Shells better. Unlike the goto-based version, functions may only be called if they were previously declared (i.e:
no forward jumps), making a similar behavior to Bourne-compatible Shells.</div>
<div><br>
</div>
<div>This new version relies on a tree derived from variables and aliases. Unlike to aliases and variables, the tree is restrictive. Once a function is declared, may not be redeclared or undeclared.</div>

</div>
<div>I was afraid this wouldn't work out for some operations, such as loops and gotos, because pipes cannot rewind. Fortunately, I was wrong, and the fact these operations are possible from interactive sessions, from a terminal, makes the assumption just as
wrong, though I'm clueless as to how the Shell handles rewinding on unsupported sources.</div>
