Let's be philosophical. Please discuss the pros and cons of each of these approaches;

approach 1

$notice = 'please be sure that XXX is installed first';

print $notice;

approach 2 (most english-like)

sub notice {  'please be sure that XXX is installed first' }
print notice;

[download]

approach 3(most coarse-grained)


sub print_notice { 
 'please be sure that XXX is installed first' 
}
print_notice;

[download]

my feeling is that approach 3 is the worst because it is not re-usable - it did not couple the core capability to print with the core capability to define strings, hence this monolithic approach prohibits print_notice from being reused for other notification possibilities (unless print returns what it prints, but even then it looks funny to have the word print there in other contexts : length print_notice vs  length notice vs.  length $notice

In reply to print_notice or print $notice or print notice? by princepawn
