Dyneval не принимает строку в фигурных скобках

[AleksVersus]

Вот такой код:

@html_it($dyneval({
	local i = rand(0,3)
	if i = 0: $result = 'string 1' & exit
	if i = 1: $result = 'string 2' & exit
	if i = 2: $result = 'string 3' & exit
	if i = 3: $result = 'string 4' & exit
}), 'underhead')

Вот такая длиннющая ошибка:

Error in Ln: 35 Col: 31
$screen_ += @html_it($dyneval({
                              ^

Код валидный, то есть QSP его прекрасно воспроизводит, однако расширению, как я понял, не нравится именно, что dyneval принимает строку в фигурных скобках, а не в кавычках.
