The issue is a very important one, because many times developers have no 
control over the characters in the keys of map-backed propeties.  A solution 
could be to enhance the expression syntax to recognize escape sequences inside 
the parenthesis representing map-backed property keys.

Consider this example:

Line 1: myBean.setMyMapBackedProp("foo).bar(baz", "myValue");
Line 2: myBean.getMyMapBackedProp("foo").setBar("baz", "myValue);

Line 3: BeanUtils.setProperty(myBean, "myMapBackedProp(foo).bar
(baz)", "myValue");

Line 3 would currently have the same effect as Line 2.  What if we want to use 
BeanUtils to achieve the effect of Line 1 instead of the effect of Line 2?  

Suppose that BeanUtils expression syntax for map-backed property keys were 
enhanced slightly to recognize these escape sequences:
"\(" for "("
"\." for "."
"\)" for ")"

Then we could use BeanUtils to achieve the effect of Line 1 as follows:

Line 4: BeanUtils.setProperty(myBean, "myMapBackedProp
(foo\.bar\(baz)", "myValue");
