[R] reading multiple key=value pairs per line

Thanks for a great environmentfor statistical computing :-)
I have some input data in a file ("input_kvpairs.csv") of the form
key1=23, key2=67, key3="hello there"
key1=7, key2=22, key3="how are you"
key1=2, key2=77, key3="nice day, thanks"
Now in my head I wish it was of the form ("input.csv")
#key1, key2, key3
23, 67, "hello there"
7, 22, "how are you"
2, 77, "nice day, thanks"
so I could do
data <- read.csv("input.csv", header=TRUE)
where the header column names are derived from the key names dynamically,
and I could access the data using normal data$key1 or data$key2 mechanism.
I guess I could just pre process the file first using python etc to create
a CSV file with column header derived from key names, and values derived
key values, but I am interested to see how experienced R folks would
