Re^2: how to force scalar context (without scalar())?

I search for a way to list parameter to a function nicely.

function(
  aa => otherfunction(),
  bb => anotherone()
);
[download]

but sometimes these functions return a list even if I'm only interested in the scalar value. so I write:

function(
  aa => otherfunction(),
  bb => scalar( anotherone() )
);
[download]

function(
  aa => otherfunction(),
  bb => anotherone() || ''
);
[download]

but scalar() is a bit ugly and || something may change my return value. So I end up in using scalar or

my $another = anotherone(); 
<code>
function(
  aa => otherfunction(),
  bb => $anotherone
);
[download]

I just search for a nicer look for a scalar like function. Using a sub ss ($) { $_[0] } is not a real option for me. But perhaps something other can provide the same functionality.

Ah, assignment… of course. You can inline it: `function( aa => ( my $aa = otherfunction() ), bb => ( my $bb = anotherone() ), );` [download] That's all the options available. Makeshifts last the longest.	[reply] [d/l]

That exactly answer my question. Thanks. Boris	[reply]

I really really wonder how you can think that `func( aa => (my $aa = foo()), bb => (my $bb = bar()), );` [download] can be prettier than `func( aa => scalar foo(), bb => scalar bar(), );` [download] One can argue code aesthetics all day, but your assignment can be a real pain in the long run and all it does is to fool the maintenance programmer into thinking that you especially want those values later. If you do this, although please don't, at least use a `do` block to handle the scoping issue (and make the maintenance programmer scratch his head a little less). `func( aa => do { my $t = foo() }, bb => do { my $t = bar() }, );` [download] `ihb` Read argumentation in its context!
