Try-Catch clause fails in evalin

Wondering if someone knows why try-catch syntax fail to work inside an evalin('caller',expression)? Are there any workarounds? Additionally, the following doesn't work, although I kind of expected it to.
try
evalin('caller',expression1);
catch E
evalin('caller',expression2);
end
My reason for even wanting to use these horrible statements (bad code practice) is to write a save function wrapper that by default picks faster compressionless saves unless it fails (usually for reasons of file size for compressionless save). And of course variables for the save() process are in the calling workspace.

It does appear to generally work:
>> try; evalin('base','fooor'); catch ME; disp('caught'); end
caught
However, there are some errors that cannot be caught, including running out of memory and exceeding the recursion limit.
