[EP-tech] Re: Random question: Eprint core fields

[John Salter]

It was more the coding-standards inconsistencies I was thinking about (hence the pedant hat).

For you and I it doesn't matter. To someone picking up eprints, and perl as a new language, it could be confusing.

Single quotes won't extrapolate a variable (and characters such as \n, 
\r) while double quotes will:

my $var1 = 'hello';
my $var2 = '$var1 world';
my $var3 = "$var1 world";

print $var2;    # will print <$var1 world>
print $var3;    # will print <hello world>
