Is there simple to use logic that equals "if a field exists, then…":
if( **fieldname__c exists** ) then { ... }
..? I really don't want to have to worry about a ton of class or other logic. I'm hopeful someone has a clue what to replace the if clause with, because I have no idea.
This is to come up with a much more simplistic fix for a problem I've been trying to resolve via two other questions. :-/
1: After Delete – Need To "Cleanup" When An Opp Is Deleted
2: Apex TRY … CATCH … FINALLY Syntax
Having this would give me the solution I need (but more specifically that I want without having a ton of code or yet another Trigger).
Added Note: My fallback IS GOING to be the TRY-CATCH logic. I'm just hopeful there is something more elegant / appropriate.

Use the Describe methods. In the example below, replace
My_Object__c
with the name of the pertinent sObject.Note, don't repeatedly call
Schema.SObjectType.My_Object__c.fields.getMap()
as there are governor limits around describe calls. Call it once and save the list.
