extracting values from equations



I have a list of results from a function call in the following form:  
[x=1,x=2,...,x=53] and I want to get a list of just the numbers by  
themselves without having to manually get them by hand. That is I  
wish to get the list [1,2,...,53]. What is the best way to achieve  
this in maxima?

Regards,

Ruben
