Re^2: catch die from say

"say $mail $textecourriel;"

From perlobj: Indirect Object Syntax (emboldened text from the documentation):

Outside of the file handle case, use of this syntax is discouraged as it can confuse the Perl interpreter. ...

Also, the "The 'indirect' feature" is disabled in v5.36 (see "perl5360delta: use v5.36").

I would recommend

$mail->say($textecourriel);
[download]

as a preferred syntax.

Update: See responses for why I have striken this recommendation.

That's all wrong. `say $mail $textecourriel;` is NOT an instance of indirect method call syntax. It's not a method call at all. It's a named operator with a funky syntax. The `indirect` feature has no effect on this. (Neither does the `indirect` pragma.) It does NOT confuse the Perl interpreter (because `say` is always declared, and because the handle expression is limited to a simple scalar, a bareword (if you use the `bareword_filehandles` anti-feature), or a block). Unlike `say $mail $textecourriel;`, `$mail->say( $textecourriel );` does invoke a method (of IO::Handle). This adds needless overhead and complexity. This is what should be avoided. The `IO::Handle::say` method doesn't use `say`. It instead emulates it using `local $\ = "\n";` and `print`. This is not equivalent in an (admittedly obscure) corner case. The `IO::Handle::say` method ends up using `print $mail $textecourriel;` anyway. Because that's how one prints to a file handle in Perl. It's not something to avoid as you suggest. If it's in perlfunc, it's not a method call. As such, none of the following are instances of indirect method call syntax: `print FH LIST` `print BLOCK LIST` `printf FH LIST` `printf BLOCK LIST` `say FH LIST` `say BLOCK LIST` `map BLOCK LIST` `grep BLOCK LIST` `system BLOCK LIST` `exec BLOCK LIST`	[reply] [d/l] [select]
