People don't always think about things in a consistent way. We naturally tend to vary the way we think and speak. An intuitive language should be consistent in its behavior but flexible regarding the way things are expressed, to accommodate some variation in the way commands and expressions are written.
Many operators can be expressed in multiple ways. Some commands support a flexible syntax that allows the order of phrases to be varied (replace command, sort, etc.). Many different date formats are recognized.
if foo < bar
if foo is less than bar

replace comma with colon in text
