Avoid the issue outlined in #2289 where the @if or @else is taken as the statement of an `if`, `for` or `while` by rejecting such constructs. Effectively this means the following scripts are now rejected: # Print's "cond true" with Zeek 5.0 even though the `if ( F )` # should be in effect. if ( F ) @if ( T ) print "cond true"; @else print "cond false"; @endif or # Print's "hello" once with Zeek 5.0 local v = vector( 1, 2, 3 ); for ( i in v ) @if ( T ) print("hello") @endif To make above work as intended, additional braces can be used. if ( T ) { @if ( cond ) print "cond true"; @else print "cond false"; @endif } for ( i in v ) { @if ( T ) print("hello") @endif }
