[Bug]: Compilation fails when do clause is present after an aggregation

[LakshanWeerasinghe]

Description

Below ballerina code is a syntactically and semantically correct. But when we compile it gives compile-time errors.

function total(float[][] items) {
    from var i in items
    let float tot = from var j in i collect sum(j)
    do {
        
    };
}

Compile time errors are,

invalid expression statement
missing select clause
incompatible types: expected 'float', found '()'
