Issues(en-bn)

• In the rule "SN SV SN" in t2x, case for the last SN is forced <obj>. This is not right all the time; say,

  "I eat fish" → "আমি মাছকে খাই"

this should be "আমি মাছ খাই", whereas,

  "I love you" → "আমি আপনাকে ভালবাসি"

is ok with case <obj>.

• About the future perfect tense, it should like this:

  "I shall have eaten rice" → "আমি ভাত খেয়ে থাকব"

But we don't have inflections for the verb 'খ/া' for 'েয়ে থাকব'
