That is not exactly true. <cfif myvar> will evaluate true for any non-zero
value (or the boolean true) while <cfif myvar is true> implies that the
comparison is being done on a variable that is a boolean and set to true.
<cfparam name="myvar" default=2>
<cfif myvar>
<!--- true --->
</cfif>
<cfif myvar is true>
<!--- false --->
</cfif>
