Description
In a parameter tree of the form
setting = 0.5
the value of "setting" can be accessed as
int setting = ptree.get("setting");
This will set setting to 0, without any diagnostic.
I propose to issue an error (e.g. throw an exception) in get() when parts of the value cannot be parsed.
The version of get() with a default argument need some more research. It is clear that a string that cannot be parsed should not result in the default value, but in an error. It is however not clear what should happen if the option is set to a string containing only whitespace.
Liesel Schuhmacher (Münster) ran into this problem.
