method trim(Str:D: --> Str)
Remove leading and trailing whitespace. It can be used both as a method on strings and as a function. When used as a method it will return the trimmed string. In order to do in-place trimming, one needs to write .=trim
my $line = ' hello world ';
say '<' ~ $line.trim ~ '>'; # OUTPUT: «<hello world>»
say '<' ~ trim($line) ~ '>'; # OUTPUT: «<hello world>»
$line.trim;
say '<' ~ $line ~ '>'; # OUTPUT: «< hello world >»
$line.=trim;
say '<' ~ $line ~ '>'; # OUTPUT: «<hello world>»
