mlhii has asked for the wisdom of the Perl Monks concerning the following question:

while constructing an anonymous array to pass as a reference to the Net::SNMP trap method i noticed that the asn.1 constants could not be quoted in the array. the following does not work: $vb= ".1.3.6.1.4.1.759.1.1.5.3", "OCTET_STRING", "SNMP Agent down"; once the quotes were removed the constant OCTET_STRING was recognized. could find no data explaining why. any thoughts monks? thanks.

    Constants are not interpolated into quoted strings (unless you use one of the tricks to interpolate code, e.g. "@{[OCTET_STRING]}".

    Constants are actually implemented as subroutines (though the actual call is optimized away). Just as "x foo() y" doesn't call foo, "OCTET_STRING" is just a string, not a call to OCTET_STRING.
