Just curious if there is a more elegant way to set a variable if it happens
to not exist yet. I often find I am doing somthing like the following:
regex = ''
10.times { regex += '.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*\n' }
Is there some prettier way to within the second line create the variable if
it does not exist yet? The above just looks ugly. I know I could use a class
variable but that also does not seem right as I do not need it to be a class
variable:
10.times { @regex += '.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*,.*\n' }
