Can not use same function more than one time in same template

[payalshah15]

I am assigning " test string " value to myVar variable and printing it.
{assign 'test string' myVar}
{$myVar}

I want to create an array user using assign and print its value.
{assign array(name="Bob" gender="male") user}
{$user.name} is {$user.gender}*}

I want to use above both code in one template which is not working.

Error is :- Cannot redeclare Dwoo\Plugins\Functions\functionAssignCompile() .....
