If only it

Here's one possibility: you can use one of the PObj_private PMC flags to
store the defined/undefin

$alias = undef
translates to
null $P1
$P2 = getinterp
$P2 = $P2["lexpad"; 1]
$P2['$alias'] = $P1
Given that you are using DynLexPad, you just do:
delete $P2['alias']

While working out some bugs in ParTcl I came across something roughly
equivalent to the following Perl code (I'm using Perl because I
believe more people know Perl than Tcl, at least on this list):
#!/usr/bin/perl
$var = "Foo";
*alias = *var;
$alias = undef;
$alias = "Baz";
print $va
