Can't redefine variables in tuples

[mr-zwets]

It would be clean if cashscript allowed to redefine variables in tuples, for example:

bytes variableA = 0x00;
bytes variableB = 0x00;
if(condition){
  variableA,variableB = bytesequence.split(index); 
}

Currently the workaround is

bytes variableA = 0x00;
bytes variableB = 0x00;
if(condition){
  variableA = bytesequence.split(index)[0]; 
  variableB = bytesequence.split(index)[1];
}
