[Quantlib-dev] what about EIBTI idiom ?

[DU V. DE V. F. G. P. <fra...@ca...>]

Hi all,


I don't want to diminish my fault (sorry again folks). However, the fact =
that this bug has been made possible by a default argument remind me the =
following verse:=20

Explicit is better than implicit.=20
(The Zen of Python, by Tim Peters)

IMHO default parameters can help to save typing but can also form nasty =
traps in that they provide quite realistic wrong values and thus hard to =
detect bugs. (In this case I have been quite lucky that this bug show =
up). I would even dare to say that sometimes they might even reduce code =
explicitness.
Any thoughts ?=20

Probably this change:

struments/bond.cpp?r1=3D11869&r2=3D11868&pathrev=3D11869>

It seems that one of the two settlementDate() calls got lost...
