According to VBA spec the max length of a function name could be 255 characters. But due 
some bug in the MacOS version, VBA crashes on function names longer than 59 characters. If
the bug gets worse it can save some effort to shorten the function names on the shell.

How to change function name length for step definition classes:

* cd into step_definitions dir
* inline edit step definition files using sed:
	sed -r -I '.bak' 's/^([a-zA-Z0-9_ ]{1,56})[a-zA-Z0-9_ ]*_([A-F0-9]{12}\()/\1_\2/' Steps*.cls
	// length of the first regex pattern is target length - 2
	// for example if target length for function names is 58 characters, then length of the first pattern is 56
* validate result with perl oneliner:
    ls Steps* | xargs perl -ne '/\bsub\s+(\w+)\(/i and printf "%2.2d: %s  - %s\n", length($1), $1, $ARGV'
* remove backup files
	rm *.bak
