Well, I don't think it is quite like leaving out a period. A period is a required function to denote the closing of a sentence.
Pound signs are only required when a variable explicitly needs to be evaluated. The rest of the time they are optional. And your example: <cfset variables.my_var = "#query.column#"> is flawed because if the value of query.column holds a numeric value, it will be converted to a string. The way the statement is structured, someone reading that line would read that the intention of the statement is to assign a STRING to the variable my_var. If the variable query.column holds a numeric value then this statement is misleading and incorrect. Because Cold Fusion is untyped, this USUALLY does not pose problems but it could potentially cause problems. And as for your other example: <cfset variables.my_var = "query.column"> This statement puts the STRING "query.column" into the variable my_var. You are not getting the value of the query.column variable.

Importance: Low I understand your point, but it is like saying periods clutter up pages in a book. If you have: <cfset variables.my_var = "#query.column#"> That tells me that there is a variable being set and it is a string <cfset variables.my_var = "query.column"> Am I setting my variable to the two words seperated by a period, query.column? or to a variable query.column? To each his own, but it makes more sense to me to see those pounds on the right hand side ..
