Of Perl:

22. Avoid {}
: Never put in any { } surrounding your if/else blocks unless they are syntactically obligatory.
If you have a deeply nested mixture of if/else statements and blocks, especially with misleading
indentation, you can trip up even an expert maintenance programmer. For best results with
this technique, use Perl. You can pepper the code with additional ifs after the statements,
to amazing effect.

...

Perl Only
: Use trailing if's and unless's especially at the end of really long lines.
