[[PRE:
wantarray
]]
----
ALIGN::left
wantarray
Returns true if the context of the currently executing
subroutine or "eval" is looking for a list value. Returns false
if the context is looking for a scalar. Returns the [[EM:undefined]]
value if the context is looking for no value ([[EM:void context]]).
----
ALIGN::left
true : list
false : scalar
undef : void
----
Scalar Context
[[PRE:
my $out = $js->alert(42);
]]
----
Void Context:
[[PRE:
$js->alert(42);
]]
----
ALIGN::left
Scalar context
[[EM:$js->jQuery("#foo")]]->show(42);
Outputs
jQuery("#foo")[[EM:.]]
----
ALIGN::left
Void context
$js->jQuery("#foo")->[[EM:show(42)]];
Outputs
jQuery("#foo").show()[[EM:;]]
----
TODO:

ALIGN::left
❏ Closure / Scope
❏ Context ([[EM:this]] variable)
❏ prototype / meta
❏ helper to specific libraries

Goal:
❏ Completely writes a JSAN module
