Actually, more like chain(stringx, 'trim', 1,'repeatchars',5, 'upper',
nil, ' test ').
Another idea is chain(stringx):trim():repeatchars(5):upper()(' test
'), which may be preferable to the current approach in
MethodChainingWrapper. That even allows separation and reuse like
f = chain(stringx):trim():repeatchars(5):upper()
print ( f(' test ') )
print ( f(' again ') )
