Compile error: 'EUDVariable' object has no attribute 'fields', when `a[0]` used as logical operand

[Chromowolf]

For euddraft0970 and later versions:

const a = PVariable();

function onPluginStart() {
    if (a[0]) {  // a[0]>0 also error
        // some statement
    }
}

Compile error: [Error] 'EUDVariable' object has no attribute 'fields'

This should be fixed in euddraft 0.9.7.4.

But new issue remains while moving optimizing pass from eudplib to epScript. In euddraft 0.9.7.4, if (a[0]) will call subscript while if (a[0] > 0) does in-place comparison. :(

Fixed confirmed in euddraft 0.9.7.7
